“Just so; but why _both_ sheets? One would be ample. And since you allude to the bundle, why both sheets as well as the Indian shawl? This last, by the way, is a thing Mrs. Beckle seems not to have missed in the confusion, or perhaps she didn’t know that Pullin possessed it. Why all these wrappings, and moreover, _why the hook?_ The presumption is clear. The bundle was already made up in the Indian shawl, and required no more wrapping. The two sheets were wanted to tie together to enable the criminal to descend from the window, and the hook was the very thing to hold this rope with at the top. It was not necessary to tie it to anything, and it would not prevent the shutting of the window behind. Moreover, when the descent had been made, a mere shake of the rope of sheets would dislodge the hook and bring it down, thus leaving no evidence of the escape--except the mark on the sill, which was very small. “Then again, there was no noise or struggle heard. Pullin, as you could see, was a powerful, hard-set man, not likely to allow his throat to be cut without a lot of trouble, therefore the murderer must either have entered the room unknown to him--an unlikely thing, for he had not gone to bed--or else must have been there with his permission, and must have taken him by sudden surprise. And now we come to the heart of the thing. Of the two papers burnt in the grate--you have kept them under the shade, I see--one bore no trace of the writing that had been on it (many inks and papers do not after having been burnt), but the other bore plain signs of having been a cheque. Now just let us look at it. The main body of the paper has burnt to a deep gray ash, nearly black, but the printed parts of the cheque--those printed in coloured inks, that is--are of a much paler gray, quite a light ash colour. That is the colour to which most of the _pink_ ink used in printing cheques burns, as you may easily test for yourself with an old cheque of the sort that is printed from a fine plate with water-solution pink ink. The _black_ ink, on the other hand, such as the number of the cheque is printed in, has charred black, and by sharp eyes is quite distinguishable against the general dark gray of the paper. The cinder is unfortunately broken rather badly, and the part containing the signature is missing altogether. But one can plainly see in large script letters part of the boldest line of print, the name of the bank. The letters are _e r n C o n s o,_ and this must mean the Eastern Consolidated Bank. Of course you saw that for yourself.” “Yes, of course I did.”
