'I think so. Look here, for example. Certain letters get habitually mixed up in typewriting; _c_ and _v_ stand next one another on the keyboard of the machine, and the person who typed this draft sometimes strikes a _c_ instead of a _v_, or _vice versa_. I never do that. The letters I tend to confuse are _s_ and _w_, or else _e_ and _r_, which also come very near one another in the arbitrary arrangement. Besides, when I type-wrote the original of this will, I made no errors at all; I took such very great pains about it.' 'And this person did make errors?' 'Yes; struck the wrong letter first, and then corrected it often by striking another rather hard on top of it. See, this was a _v_ to begin with, and he turned it into a _c_. Besides, the hand that wrote this will is heavier than mine: it comes down _thump_, _thump_, _thump_, while mine glides lightly. And the hyphens are used with a space between them, and the character of the punctuation is not exactly as I make it.' 'Still,' Mr. Hayes objected, 'we have nothing but your word. I'm afraid, in such a case, we could never induce a jury to accept your unsupported evidence.' 'I don't want them to accept it,' I answered. 'I am looking this up for my own satisfaction. I want to know, first, who wrote this will. And of one thing I am quite clear: it is _not_ the document I drew up for Mr. Ashurst. Just look at that _x_. The _x_ alone is conclusive. My typewriter had the upper right-hand stroke of the small _x_ badly formed, or broken, while this one is perfect. I remember it well, because I used always to improve all my lower-case _x_'s with a pen when I re-read and corrected. I see their dodge clearly now. It is a most diabolical conspiracy. Instead of forging a will in Lord Southminster's favour, they have substituted a forgery for the real will, and then managed to make my poor Harold prove it.' 'In that case, no doubt, they have destroyed the real one, the original,' Mr. Hayes put in. 'I don't think so,' I answered, after a moment's deliberation. 'From what I know of Mr. Ashurst, I don't believe it is likely he would have left his will about carelessly anywhere. He was a secretive man, fond of mysteries and mystifications. He would be sure to conceal it. Besides, Lady Georgina and Harold have been taking care of everything in the house ever since he died.' 'But,' Mr. Hayes objected, 'the forger of this document, supposing it to be forged, must have had access to the original, since you say the terms of the two are identical; only the signatures are forgeries. And if he saw and copied it, why might he not also have destroyed it?'
