藤荘（26）

“We can now see a reason for the disappearance of Garcia's household. They were all confederates in the same unknown crime. If it came off when Garcia returned, any possible suspicion would be warded off by the Englishman's evidence, and all would be well. But the attempt was a dangerous one, and if Garcia did not return by a certain hour it was probable that his own life had been sacrificed. It had been arranged, therefore, that in such a case his two subordinates were to make for some prearranged spot where they could escape investigation and be in a position afterwards to renew their attempt. That would fully explain the facts, would it not?”

The whole inexplicable tangle seemed to straighten out before me. I wondered, as I always did, how it had not been obvious to me before.

“But why should one servant return?”

“We can imagine that in the confusion of flight something precious, something which he could not bear to part with, had been left behind. That would explain his persistence, would it not?”

“Well, what is the next step?”

“The next step is the note received by Garcia at the dinner. It indicates a confederate at the other end. Now, where was the other end? I have already shown you that it could only lie in some large house, and that the number of large houses is limited. My first days in this village were devoted to a series of walks in which in the intervals of my botanical researches I made a reconnaissance of all the large houses and an examination of the family history of the occupants. One house, and only one, riveted my attention. It is the famous old Jacobean grange of High Gable, one mile on the farther side of Oxshott, and less than half a mile from the scene of the tragedy. The other mansions belonged to prosaic and respectable people who live far aloof from romance. But Mr. Henderson, of High Gable, was by all accounts a curious man to whom curious adventures might befall. I concentrated my attention, therefore, upon him and his household.
