Nothing, however, like legal evidence appeared against him, and the consequence was that the verdict was found against a person or persons unknown; and for some time the matter was suffered to rest, until, after about five months, my father received a letter from a person signing himself Andrew Collis, and representing himself to be the cousin of the deceased. This letter stated that Sir Arthur was likely to incur not merely suspicion, but personal risk, unless he could account for certain circumstances connected with the recent murder, and contained a copy of a letter written by the deceased, and bearing date, the day of the week, and of the month, upon the night of which the deed of blood had been perpetrated. Tisdall's note ran as follows: 'DEAR COLLIS, 'I have had sharp work with Sir Arthur; he tried some of his stale tricks, but soon found that _I_ was Yorkshire too: it would not do--you understand me. We went to the work like good ones, head, heart and soul; and, in fact, since I came here, I have lost no time. I am rather fagged, but I am sure to be well paid for my hardship; I never want sleep so long as I can have the music of a dice-box, and wherewithal to pay the piper. As I told you, he tried some of his queer turns, but I foiled him like a man, and, in return, gave him more than he could relish of the genuine DEAD KNOWLEDGE. 'In short, I have plucked the old baronet as never baronet was plucked before; I have scarce left him the stump of a quill; I have got promissory notes in his hand to the amount of--if you like round numbers, say, thirty thousand pounds, safely deposited in my portable strong-box, alias double-clasped pocket-book. I leave this ruinous old rat-hole early on to-morrow, for two reasons--first, I do not want to play with Sir Arthur deeper than I think his security, that is, his money, or his money's worth, would warrant; and, secondly, because I am safer a hundred miles from Sir Arthur than in the house with him. Look you, my worthy, I tell you this between ourselves--I may be wrong, but, by G--, I am as sure as that I am now living, that Sir A---- attempted to poison me last night; so much for old friendship on both sides.
