When I left my chambers, with an automatic pistol, a case of sandwiches, and a flask of whisky-and-water, the rain was descending in a torrent. The street was empty and dismal, and Berkeley Square itself a desert. I don't think I saw a single person, except one police-constable in oilskins sheltering under an archway, till I arrived at Birmingham House. The well-known façade of the mansion was blank and cheerless. All the blinds were down; there was not a sign of occupation. I rang, the door opened immediately, and I slipped in.
"I must be off, Sir Thomas," said Sliddim. "If you go through the door on the far side of the inner hall beyond the grand staircase, you will find yourself in a short passage with a baize door at the farther end. Push this open, and you will be in a small lobby. The door immediately to your left is that of the butler's pantry. It commands the service stairs and lift to the kitchen and servants' rooms. Standing in the doorway you will see the head of any one coming up the stairs, and—" he gave a sickly grin and something approaching a reptilian wink. Sliddim was an unpleasant person, and I never liked him less than at that moment.
With another whisper he opened the door a few inches and writhed out.
I was left alone in Birmingham House.
It was the queerest possible sensation, and as I crossed the great inner hall, with its tapestries and gleaming statuary, lit now by two single electric bulbs, I don't deny that my heart was beating a good deal faster than was pleasant. There is always something ghostly about an empty house, more especially when it is fully furnished and ready for occupation. The absence of all life is uncanny, and one seems to feel that it is hidden, not absent, and that at any moment a door may open and some enigmatic stranger be standing there with an unpleasant welcome in his eyes.
Well, I slunk through all the glories of the grand hall, passed down the passage, and came out into the servants' quarters. The little lobby, the floor of which was covered with cork matting, was well lit, and so were the stairs. I peered over the rail, but could not see to the bottom; but, standing in the door of the room called the butler's pantry, I saw that I could put a bullet through the head of any one appearing, before he could have the slightest inkling of my presence, before he could slew round, even, to face me.
The butler's pantry itself was a fair-sized, comfortable room, with a carpet on the floor and a couple of worn, padded armchairs by the fireplace. The walls were hung with photographs; on one side was a business-like roll-top desk, and in a corner a large safe which obviously contained the plate in daily use in the great household. I knew that the bulk of the valuables were stored in a strong room in Chancery Lane.
Upon the table Mr. Sliddim had thoughtfully placed a heavy cut-glass decanter half full of whisky, a siphon, and—glasses! The whisky was all right, but did he expect me to hobnob with Antony Midwinter, to speed the parting guest, as it were, with a stirrup-cup? It was difficult to suspect him of such grim humor.
I looked at my watch. There was still a good half-hour before Midwinter and Sliddim were due to meet in the little public house behind the Square. I saw that my pistol was handy, and sat down in one of the armchairs by the fireside. A pipe of the incomparable "John Cotton" would not be amiss, I thought, wondering if I should ever taste its fragrance again, and for some minutes I sat and smoked, placidly enough. Then, I suppose a quarter of an hour or so must have elapsed, I began to fidget in my chair.
The house was so terribly still! Still, but not quite silent! Time, that was ticking away so rapidly, had a score of small voices. There was the faint noise of taxicabs out in the Square, the drip of the rain, an occasional stealthy creak from the furniture, the scurry of a mouse in the wainscot; the more remote chambers of my brain began to fill with riot, and once my nerves jerked like a hooked fish.
