I often wonder why the pantry window is the vulnerable point of nine houses out of ten. This house of ours was almost the tenth, for the window in question had bars of sorts, but not the right sort. The only bars that Raffles allowed to beat him were the kind that are let into the stone outside; those fixed within are merely screwed to the woodwork, and you can unscrew as many as necessary if you take the trouble and have the time. Barred windows are usually devoid of other fasteners worthy the name; this one was no exception to that foolish rule, and a push with the pen-knife did its business. I am giving householders some valuable hints, and perhaps deserving a good mark from the critics. These, in any case, are the points that I would see to, were I a rich stockbroker in a riverside suburb. In giving good advice, however, I should not have omitted to say that we had left our machines in the semi-circular shrubbery in front, or that Raffles had most ingeniously fitted our lamps with dark slides, which enabled us to leave them burning. It proved sufficient to unscrew the bars at the bottom only, and then to wrench them to either side. Neither of us had grown stout with advancing years, and in a few minutes we both had wormed through into the sink, and thence to the floor. It was not an absolutely noiseless process, but once in the pantry we were mice, and no longer blind mice. There was a gas-bracket, but we did not meddle with that. Raffles went armed these nights with a better light than gas; if it were not immoral, I might recommend a dark-lantern which was more or less his patent. It was that handy invention, the electric torch, fitted by Raffles with a dark hood to fulfil the functions of a slide. I had held it through the bars while he undid the screws, and now he held it to the keyhole, in which a key was turned upon the other side. There was a pause for consideration, and in the pause we put on our masks. It was never known that these Thames Valley robberies were all committed by miscreants decked in the livery of crime, but that was because until this night we had never even shown our masks. It was a point upon which Raffles had insisted on all feasible occasions since his furtive return to the world. To-night it twice nearly lost us everything—but you shall hear. There is a forceps for turning keys from the wrong side of the door, but the implement is not so easy of manipulation as it might be. Raffles for one preferred a sharp knife and the corner of the panel. You go through the panel because that is thinnest, of course in the corner nearest the key, and you use a knife when you can, because it makes least noise. But it does take minutes, and even I can remember shifting the electric torch from one hand to the other before the aperture was large enough to receive the hand and wrist of Raffles.
