Then, why? How to explain it? Here was a young country gentleman, highly popular; if he had enemies, they would not be outside his own part of the country. Most country gentlemen, in those days, had many enemies. These enemies, who were rustics for the most part, satisfied their revenge and their hatred by poaching on the preserves. They also set fire to the hayricks. Langley Holme was staying a welcome guest with his friend and brother-in-law; he was walking along on a summer morning in a wood not a mile away from the House and Park, and there he was discovered lying dead—murdered!

It may be objected that this attempt to solve the insoluble after seventy years was a waste of time; that dead and gone crimes may as well be left alone. Other people’s crimes may no doubt be left alone. But this was his own crime, so to speak—a crime inflicted in and upon his own family. Besides, he was dragged by ropes to the consideration of the thing; his mind was wholly charged with it; he could think of nothing else.

Presently he shaped a theory, which at first seemed to fit in with everything. It was really a very good theory, which promised, when he framed it, to account for all the facts brought out in the inquest and at the trial.

The theory supposed an escaped lunatic—a homicidal maniac, of course; that would account for everything. A maniac—a murderous maniac. He must have been lying concealed in the wood; he must have rushed out armed with his club, like that gorilla. This theory seemed to meet every point in the case. He shut up the book; he had found out the truth; he could now go about his own work again, forgetting the mysterious murder which drove his great-grandfather off his balance.

He sighed with satisfaction. He placed the book in a drawer out of the way; he need not worry any more about the thing. So with another sigh of relief he reached out for his books and returned once more to the study of his “subject.”

Presently he became aware that his eyes were resting on the page without reading it; that his mind was back again to the Book of Extracts, and that in his brain there was forming, without any volition of his own, one or two difficult questions about that maniac. As, for instance, if there had been such a creature wandering in the fields someone would have seen him; he would probably have murdered more than one person while he was in the mood for murder. There was a little boy, for instance, scaring birds; he would have killed that little boy. Then, the fact of a roving maniac would have been known. He must have escaped from somewhere: his madness must have been known. There would have been some sort of hue and cry after him: either at the inquest or at the trial there would have been some mention of this dangerous person going about at large; some suggestion that he might have been the guilty person. Dangerous maniacs do not escape without any notice taken, or any warning that they are loose.

No. It would not do. Another and a more workable theory must be invented.

He got another. Poachers! Everybody knows the deadly hostility, far worse seventy years ago than at present, that existed between a country gentleman and a poacher. The latter was accustomed, in those days, to get caught in a mantrap; to put his foot into a gin; to be fired upon by gamekeepers; to be treated like a weasel or a stoat. In return the poacher manifested a lamentably revengeful spirit, which sometimes went as far as murder. In this case, no doubt, the crime was committed by a poacher.

The theory satisfied him at first, just as much as its predecessor. Presently, however, he reflected that there is not much for a poacher to do in early June, and that poachers do not prowl about the woods and coverts in broad daylight and at noon; and that poachers do not, as a rule, murder gentlemen belonging to other parts of the country. Besides, poachers on one estate would not bear malice against the squire of another estate fifteen miles distant. Leonard pushed his papers away in despair.

Any other kind of work was impossible; he could think of nothing else. At this point, however, some kind of relief came to him. For he felt that he must make himself personally acquainted with the place itself. He wanted to see the wood of which so much mention was made—the place where the blow was struck, the place where the murderer lay hidden. He wanted the evidence of the wood itself, which was probably the same now as it had been seventy years before, unless it had been felled or built over. In that part of the country they do not destroy woods, and they do not build upon their site; it is a conservative country. As the fields were a hundred years ago, so they are now.
