“It’s a Chubb, a Bramah, or one of those lever locks,” said Boyd, in a low tone, giving it up after he had tried all the keys in vain. “It won’t do to force the door, for that’ll betray us.”

“Why not try a window?” I suggested.

“No, sir,” said the plain-clothes man. “They’re all barred, I’m afraid.”

“But those on the first floor,” I suggested, looking up at one, evidently a landing window, over the door.

“We might try if we could only reach it,” Boyd said, laying down the keys upon the doorstep. “If we forced the catch we could screw it down again before we left.”

In order to discover something by which we might gain access to the window we all three crept carefully across the lawn and down the long old-fashioned garden to an outhouse, where, after some search, we found an old and rotten ladder, half the rungs of which seemed missing. This we carried back, and a few moments later Boyd, mounting, with a strong clasp-knife which he had taken from his pocket, began slowly working back the catch, until at last he was able to throw up the window and crawl in. Without a sound I followed, the local detective clambering in after me.

We found ourselves on the first floor landing, therefore, descending the stairs to the main hall, we lit the candles provided by the plain-clothes man, and after taking the precaution to let down the blinds of the front windows, commenced an active search of the drawing-room, that spacious old-fashioned apartment into which I had been shown when I had called. Our search, directed by Boyd, was careful and methodical; neither nook nor corner escaped him, although we replaced everything just as we found it. So large were the rooms that we found the lights we carried were not sufficient to give us proper illumination, therefore we sought the gas-meter, and after turning on the gas, lit jets in the various rooms. Fortunately all the windows were furnished with Venetian blinds, therefore we let them down and closed them, so that no light should be noticed outside.

An air of desolation hung about the place, and every sound we made echoed weirdly, for at dead of night all noise becomes exaggerated. The drawing-room yielded practically nothing, therefore we passed into a well-furnished morning-room, and thence to the dining-room, which we likewise thoroughly overhauled. None of these rooms bore any trace of the struggle with poverty which the innkeeper’s wife had alleged. Indeed, in the drawing-room was a fine grand piano of one of the best-known makers, together with several rare works of art. All the rooms bore signs of being the abode of a rich and cultured family, the old oak in the dining-room being, I noted, genuine, evidently antique, Italian, while the upholstery and carpets were of the first quality. On the walls of those ground-floor rooms were many examples of old as well as modern masters, one portrait hanging in the dining-room representing Eva herself, a half-length picture, undoubtedly from recent sittings, signed by an artist extremely well-known in London. In this room also were antique high-backed oak chairs, lined with old tapestry, the back and arms bearing armorial bearings embroidered in coloured silks, evidently the arms of the Glaslyns, for a similar device was upon the plate.

On ascending to the first floor we found the house to be of far larger proportions than we had imagined, for off a long, well-carpeted corridor opened quite a number of bed and other rooms, each of which we proceeded to inspect.

“We haven’t found a single thing below,” Boyd observed to me, as we entered the first of these rooms, evidently one of the spare bedrooms, for the place was very dirty and neglected in comparison with the other apartments. “Let’s hope we may come across something here.”
