There ensued a couple of dusty and hope-deferred hours. From the smoking room, which yielded no results at all, he went to Mr. Francis's rooms, which he had fixed upon as being the most likely place for the conjectured passage to communicate with, but the strictest scrutiny of the panelling revealed nothing. He tapped every foot of it, and every foot sounded promisingly hollow, yet nothing of any sort could he discover which should yield him even a sixpence. There were cupboards of the most alluring probability; all wore the aspect of concealment, yet all declined to yield their secret.

Geoffrey had never been in this room before, and after a fruitless search he took a look round before leaving it. Orderly and industrious were the indications of its master; docketed papers lay neatly in little heaps, and the appurtenances of its stationery were finished and complete. Each set of papers had its elastic band, each its note of contents in red ink; two sets of penholders lay in separate trays, and the examination of the nibs showed that Mr. Francis was of that rare type of man who dedicated without violation certain pens to black ink, certain others to red. The pencils were all well sharpened, ink eraser was there as well as India rubber, and a taper of green wax was ready for the sealing of important envelopes. All this had a curdling fascination for Geoffrey, but at present he was on the hunt for shillings, and a detailed examination of a writing table brought him no nearer them.

The whole of the second floor he searched without success, except in so far that the discovery of gaunt, chilly bedrooms, in which a lively imagination might conjure up a pleasing thrill, could be reckoned a reward to his labours. Over most was the trail of the plumber; electric bells and light had been newly introduced, and these modern improvements jostled strangely with the faded mediæval discomfort of large, gloomy beds and tapestried hangings. Like the poor lion with no early Christian, these seemed to mourn the absence of murderous deeds; a suitable stage was set, but no actor trod the boards.

It was a somewhat disheartened adventurer who began his search on the ground floor, for the ground floor, he could not but remember, would bring but a small bill of steps to swell his revenues, unless, indeed, the yet undiscovered staircase proved to lead into the basement, and that possibility lent him fresh vigour. But dining room, billiard room, and both drawing-rooms were searched without result, and the hall was become practically the last cover. Here, indeed, something might be expected; tapestry covered two sides, the other two carried portraits, and again his search became minute. But half an hour was fruitlessly spent, and there remained only the fireplace side, where hung the portrait of old Francis.

Geoffrey looked at this a moment for inspiration.

"He knew all about it, I'll be bound," he said to himself. "Why can't the old brute speak?"

Looking at it thus, he noticed for the first time that the panel in which this picture hung was different from the panelling over the rest of the hall, which was all of linen pattern. But this one panel was plain, except for a row of small circular bosses which ran round it at wide intervals; and Geoffrey, goaded by the thought of his last good chance, mounted a chair and handled each of these in turn. The second he tried moved to the touch, and as, with a sudden upleap of hope, he turned it, something clicked within, and the whole panel, portrait and all, swung slowly out on a hinge. There seemed to be a narrow passage in the wall, continuing to right and left of the picture.

Geoffrey stood a moment on the chair, holding the panel from swinging farther, puzzled.

"He can't have jumped down from there," he said to himself. "Perhaps there is another door somewhere else. Anyhow he has his exits and his entrances," and the quotation seemed to him extraordinarily apt.
