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.
