"And now," said Gimblet, "may I visit the scene of the crime?"
Mark took him first to his uncle's bedroom; a room austere in its simplicity, with bare white-washed walls and uncarpeted floor. No one could have hidden a sheet of paper in that room, thought the detective, as he gazed round it, after he had looked, with a feeling akin to guilt, on the features of the dead peer. He had not known how to protect this man from the dreadful fate that had struck him down from a direction so utterly unexpected, and he held himself, in a way, responsible for his death.
Then young Ashiel led him away, down a wide corridor into the billiard-room, and so into another passage, at the end of which a door of stout and time-darkened oak gave access to the library. It creaked noisily on its hinges, as he pushed it open and ushered Gimblet in. They stepped into a square room, comfortably furnished, with deep arm-chairs, and a large chippendale writing-table which stood at right angles to the bow window, so placed that anyone writing at it should have the light upon his left. It was rather a dark room, the walls being lined with books from floor to ceiling, except at two points: opposite the window an alcove, panelled in ancient oak, appeared in the wall; and above the fireplace, opposite the door, the wall was panelled in the same manner and covered by an oil painting, representing Lord Ashiel's grandmother. The polished boards were unconcealed by any rug or carpet, and reflected a little of the light from the window. An ominous discoloration near the writing-table showed plainly upon them.
In the glass of the mullioned casement was the small round hole made by the fatal bullet.
Gimblet glanced at the bureau on which the writing materials were set out in perfect order, and could not conceal his annoyance.
"Everything has been moved, I see," he said. "Why couldn't they leave it as it was for a few hours longer?"
"Nothing was touched till after the police had gone," said Mark. "I confess I did not think it necessary to leave things alone once they were out of the house. Not only have the housemaids been at work in here, but I spent most of the morning here myself, going through the papers in that bureau. Will it matter much?" He spoke with evident dismay.
"Never mind," said Gimblet, "I suppose Macross's people photographed everything, and I can get copies from them, I have no doubt. By the by, what did Sir David Southern say about having been in the room while you were in bed? Did he admit it; and did he say why he moved the body?"
"He said he'd not been near the place," replied Mark, looking more perplexed and worried than ever. "I can't understand it at all," he added. "Why should he deny it to me?"
Gimblet opened a drawer in the bureau. Papers filled it, tied together in bundles and neatly docketed. They seemed to be receipted bills. He glanced at the pigeon-holes, and opened one or two more drawers. Everywhere the most fastidious order reigned.
"You have been through all these?" he asked.
"Yes, but there is a cupboard full in the smoking-room. I thought of looking into those this afternoon."
"It would be a good plan," Gimblet agreed. "Don't let me keep you," And as the young man still lingered, "I prefer," he confessed, "to do my work alone. If you will kindly get me a shooting-boot of Sir David Southern's, I shall do better if I am left to myself."
"If that is really the case," said Mark, "I have no choice but to leave you. I admit I should have liked to see your methods, but if I should be a hindrance--"
Gimblet did not deny it, and Mark departed to fetch the boots.
"This is not the identical pair," he said when he returned. "The police took those; but these come from the same maker and are nearly the same, so Blanston tells me."
"Ah, yes, Blanston," said Gimblet. "I must see him presently. Thanks very much."
Left alone, Gimblet examined the window, opening one of the small-paned casements, and measuring the space between the mullions and the central bars of iron. Satisfied as to the impossibility of any ordinary-sized person passing through those apertures, he took one more look round, and then with a swift movement drew each of the heavy curtains across the bay. They did not quite meet in the middle, as Juliet had observed. Then he made his way out into the garden through the door just outside, at the end of the passage which led from the billiard-room to the library.
The library was at the far end of the oldest portion of Inverashiel Castle. To Gimblet, examining it from the outside, it looked as if the room had been hewn out of the solid walls of the ancient fortress; for beyond the mullioned, seventeenth-century window, the wall turned sharply to the left and was continued with scarce a loophole in the stupendous blocks of its surface for a distance of fifty yards or so, where it was succeeded by the lower, less heavy battlements of the old out-works. In the angle formed by the turn and immediately opposite the window of the library, a long flower-bed, planted with standard and other rose trees, with violas growing sparsely in between, stretched its blossoming length, and continued up to the actual stones of the library wall. At the farther end of it, a thick hedge of holly bordered on the roses at right angles to the end of the battlements; while the lawn on his left was spangled with geometrically shaped beds showing elaborate arrangements of heliotrope, ageratum, calceolarias, and other bedding-out plants.
Gimblet walked slowly along the lawn at the edge of the bed, his eyes on the black peaty mould, where it was visible among the flowers. About twenty yards from the hedge, he stopped with a muffled exclamation. The bed in front of him was covered with footprints of all shapes and sizes; but plainly distinguishable among the rest were the neat nail-encrusted marks which matched the boot he held in his hand. He put it down on the ground and carefully made an imprint with it in the soil, beside the existing footmarks. It was easy to single out its fellows.
"Two extra nails," murmured Gimblet to himself, "but otherwise, the same. Probably made on the same last."
Stepping cautiously in the places where his predecessors had walked, he followed the tracks that had betrayed Sir David Southern. They were numerous and distinct; he counted fourteen of each separate foot. First Sir David would seem to have walked straight across the bed, then returned and taken up his position near the middle. He was not contented with that, it seemed, for he had walked backwards five or six paces and then moved sideways again till he was exactly opposite the opening between the curtains. Here the ground was trampled down as if he had several times shifted slightly from one place to another. Whether or not he was exactly in line with the writing-table Gimblet could not see, as its position was hidden in the obscurity behind the drawn curtains. It would want a light there to prove that, thought Gimblet; still there was no reason to doubt that it was so. There were four or five more footmarks leading back to the lawn, and over these Gimblet stooped with particular interest.
With a tape measure, which he took from his pocket, he measured the distances between the prints, entering the various figures in his notebook, beside carefully drawn diagrams. Then he picked his way to the edge of the lawn, and stood a moment considering.
Apparently he was not satisfied, for presently he retraced his steps delicately to the middle of the bed, till he was once more just behind the place where the earth was trodden down. After pausing there an instant, he turned once more, and ran quickly back to the grass, without this time troubling himself to step in the chain of footprints used previously by the police. But he had not even yet finished; and was soon crouching down again, with the tape measure in one hand and the notebook in the other, poring over the evidence preserved so carefully by the impartial soil.
At last he got up, put his measure back in his pocket, and walked slowly towards the hedge. He had nearly reached it when something at his feet arrested his attention. He bent over it curiously.
Near the edge of the grass and parallel to it, there was an indentation a little over an inch wide and about the same depth. It extended in a straight line for perhaps nine inches, and what could have caused it was a puzzle to Gimblet. The turf was unbroken, and it looked as if an oblong, narrow, heavy object had rested there, sinking a little into the ground so as to leave this strange mark. Gimblet rubbed his forehead pensively, as he looked at it.
Suddenly as his introspective gaze wandered unconsciously over the ground before him, his attention was arrested by a second mark of the same perplexing shape, which he could see behind a rose-bush, more than half-way across the bed. Stepping as near the hedge as he could, the detective proceeded to examine this duplicate of the riddle. It seemed absolutely the same, though deeper, as was natural on the soft mould, and he found, by measuring, that it lay exactly parallel to the other. What could it be, he asked himself. A moment later, still another and yet stranger impression caught his eye. It was about the same width, but not more than half as long, and rounded off at each end to an oval. It was situated about a foot from the deep indentation and rather farther from the holly hedge. A tall standard rose-tree, covered with blossoms of the white Frau Karl Drouski rose, grew near it, interposing between it and the house.
Gimblet measured it with painstaking precision; then with the help of his measurements, he made a life-size diagram of it on the page of his notebook, and studied it with an expression of annoyance. He had seldom felt more at a loss to explain anything. At length he turned and went back towards the grass.
"What a track I leave," he thought to himself, looking down ruefully at his own footprints. "What I want is--" He stopped abruptly as a sudden idea struck him; then a look of relief stole slowly over his face, and he permitted himself a gratified smile, "To be sure!" he said, and seemed to dismiss the subject from his mind.
Indeed, he turned his back upon the rose-bed, and strolled away by the side of the hedge, which was of tall and wide proportions, providing a spiky, impenetrable defence against observation, from the outside, of the rectangular enclosed garden. Half-way along it he came upon an arched opening. Passing through this, he found himself in an outer thicket, and immediately upon his right hand beheld a small shed, which stood back, modest and unassuming, in a leafy undergrowth of rhododendrons.
Gimblet pushed open the door and stepped inside.
The place was evidently a tool-house, used by the gardeners for storing their implements. Rakes, spades, forks and hoes leant against the walls; a shelf held a quantity of odds and ends: trowels, seedsmen's catalogues, a pot of paint, a bundle of wooden labels, the rose of a watering-can, and a dozen other small objects. On the floor were piled boxes and empty cases; flowerpots stood beside a bag which bore the name of a patent fertilizer; a small hand mowing-machine blocked the entrance; and a plank, too long to lie flat on the ground, had been propped slantwise between the floor and the roof. Bunches of bass hung from nails above the shelf; and on the wall opposite, a coloured advertisement, representing phloxes of so fierce an intensity of hue that nature was put to the blush, had been tacked by some admirer of Art.
Five minutes later, when Gimblet emerged once more into the open, he carried in one hand a garden rake. With this he proceeded to thread his way through the shrubbery, keeping close to the line of the holly hedge. When he thought he had gone about fifty yards, he lay down and peered under the leaves. The hedge was rather thinner at the bottom; and, by carefully pushing aside a little of the glossy, prickly foliage, he was able to make out that the end of the rose-bed he had lately examined was separated from him now only by the dividing barrier of the hedge. With the rake still in his hand, he drew himself slowly forward, gingerly introducing his head and arms under the holly, till he was prevented from going farther by the close growing trunks of the trees that formed the hedge.
It took some manoeuvring to insert the head of the rake through the fence, but he did it at last, and found a gap which his arms would pass also. Between, and under the lowest fringe of leaves on the farther side, he could see the track of his own footsteps, where he had walked on the bed. They were all, by an effort, within reach of his rake, and he stealthily effaced them. He could not see whether the garden was still untenanted, or whether the peculiar phenomenon of a rake moving without human assistance was being observed by anyone from the castle. He fervently hoped that it was not: he did not wish the attention of anyone else to be called to the puzzling marks that had mystified him; and, as the only window which looked into the garden was that of the library, he thought there was a good chance that there was no one in sight.
Cautiously and almost silently he worked his way back, and replaced the rake in the tool-house where he had found it. Then he took the small oil-can used for oiling the mowing-machine, and concealing it under his coat made towards the house. The little garden was still lonely and deserted as he walked quickly over the lawn and in at the passage door.
The library was empty as he had left it, and his first act was to draw back the curtains to their former positions on either side of the window. Then he went to the door, and, with a glance to right and left along the passage, and an ear bent for any approaching footstep, he quickly and effectually oiled the hinges and lock, so that the door closed noiselessly and without protest. When he was quite satisfied on this point, he shut it gently, and took back the oil-can to the shed.
"Now," said he to himself, "for the gun-room."
He took up Sir David Southern's shooting-boots, which he had left in the tool-house during his last proceedings, and made his way through the billiard-room into the main corridor beyond. On his right, through an open door, he peeped into a large room, obviously the drawing-room, and saw that it looked on to the front of the house. The room wore a forlorn aspect; no one, apparently, had taken the trouble to put it straight since the night of the tragedy. The blinds had been drawn down, but the furniture seemed awry as if chairs had been pushed back hastily, a little card table still displayed a game of patience half set out, and even the dead flowers in the glasses had not been thrown away.
The air was stuffy in the extreme, and Gimblet, with a disgusted sniff, pulled aside one of the blinds and threw open the window. But all at once a thought seemed to strike him. For a moment he stood irresolute, then he slowly closed the casement again, but without latching it, and after frowning at it thoughtfully walked away. He went back into the hall.
Opposite, across the corridor, rose the main staircase, wide and imposing; on each side of it a smaller passage led away at right angles to the entrance, the right-hand one giving access to rooms in the new front of the castle, one of which he knew to be the dining-room. He listened for a minute outside a door beyond it, and heard the sound of rustling papers; the smell of tobacco came to him through the key-hole. It was plain that here was the smoking-room, and that the new Lord Ashiel was at that moment engaged in it, and deep in his uncle's papers.
The little detective, as he had said, preferred to work without an audience when he could, so he left Mark to his search, and stole silently away down the passage.
He passed two more rooms, and paused at the last door, opposite the foot of a winding stair.
This, from what Juliet had said, must be the door of the gun-room.
The door opened readily at his touch, and he stepped inside and shut it behind him.
It was a small bare room, with one large deal table in the middle of it. Gun-cases and wooden cartridge-boxes were ranged on the linoleum-covered floor, and three glass-fronted gun-cabinets were hung upon the walls. One, the smallest of these, was of a different wood from the others, and bore in black letters the initials D. S.
Three or four guns were ranged in it: two 12-bore shot-guns, an air-gun, and a little 20-bore. Another rack was empty; no doubt it had held the Mannlicher rifle, which the police had carried away to use as evidence in their case for the prosecution. The door was locked and there was no sign of a key.
Gimblet turned to the other cupboards.
There were more weapons here, and a few minutes' examination showed him that, as Mark had said, he and his uncle were less particular as to where their guns were kept, for the first two that the detective glanced at bore Lord Ashiel's initial, and the next was an old air-gun with M. McC. engraved on a silver disk at the stock.
Side by side were the rifles used by the uncle and nephew for stalking, Gimblet knew from Mark that the Mannlicher was his, while Lord Ashiel had apparently used a Mauser or Ross sporting rifle, as there was one of each in the case.
Gimblet lifted down the Mannlicher and laid it on the table. This, then, was the kind of weapon with which the deed had been done. It was a .355 Mannlicher Schonauer sporting weapon of the latest pattern. He opened it and examined the mechanism, which he soon grasped. He squinted down the glistening tunnel of the barrel and even closely scrutinized the workmanship of the exterior, repressing a shudder at the meretricious design of the chasing on the lock, and passing his fingers caressingly over the wood of which the stock was made. It shone with a rich bloom, as smooth and even as polished marble, except at the butt end which was criss-crossed roughly to prevent slipping; but wood in any shape has a homely friendly feeling, as different from any the polisher can impart to a piece of cold stone as the forests, where it once stood, upright and lofty, are from the inhospitable rocks on the peaks above them.
These unpractical reflections flitted through the detective's mind, together with others of a less fantastic nature, as he put the rifle back in the rack he had taken it from. He closed the glass doors of the cabinet, leaving them unlocked, as he had found them. Then, going back to the table, he took an empty pill-box from his pocket, and with the utmost care swept into it a trace of dust from off the bare deal top.
There was barely enough to darken the cardboard at the bottom of the box, but he looked at it, before putting on the lid, with an expression of some satisfaction.
