drew on the cigarette, and then sat back. But, as I could have told him, he could not enjoy it, and, after a couple of puffs, laid aside the thing, which soon expired. Then he resumed his talk in a lighter tone.
âWhen a man really cares for proof just for proofâs sake,â he went on, âwhich means caring for truth for truthâs sake, then heâs not content with probabilityâhe wants certainty.â
Again there was a pause, and I thought that Mr. M. might be thinking that he was going to get an answer. If so, he was disappointed. I saw him glance away toward the roof of the arbor, as though waiting. Then, as the silence continued, he remarked casually: âBeautiful natural roofage the beech makesâa perfect cover. As Vergil long ago put it, â sub tegimine fagi .ââ
I saw the other glance up quickly and evidently follow Mr. M.âs eye, turning his head also to the arbor roof, then look back at Mr. M., who still did not look at him. Finally, Mr. Millum let his head sink, and he just looked at the ground. This clearly made Mr. M. see that heâd have to go farther if he was to get any more information that this man might be able to give about his self-killed friend.
âMr. Millum,â Mr. M.âs voice was quiet but very clear, âyou knew the late master of this house well. There can be no question that he was a gloomy, depressed, self-centered, and, I think we can say, suspicious man. This is the type we do, rightly, associate with suicide. But usually there is some small occasion, some âtrigger actionâ that sets alight the deep mine of despair and launches the victim out into the unknown. Could you tell me of any incident that in your opinion might have provoked Mr. Sankey to act in that final desperate wayâI mean, to use the actual method that he did? Self-indulgent men are usually timid and hate pain. A stab through the heart may be acutely painful, maynât it?â
The questioned man roused himself at that. âNot necessarily. No, not at all necessarily, there are ⦠there are cases recorded where it was evidently painlessâquite, quite!â
âEven with so unhandy an instrument as a paper knife?â
âWell, that all depends on the knack with which it was driven ⦠driven home. I recall that Mr. Sankey frequently played with the sharp little blade that he usedâan antiqueâand often quoted to me the âbare bodkinâ line from Hamletâs soliloquy on suicide.â
âDid he, indeed!â
Mr. M. had swung slowly round till he was facing Mr. Millum.
âDid he?â
The phrase which had been first question-tinged with surprise had, in the second speaking, turned suddenly into challenge.
âDid he!â
It was again spoken, and this time there could be no doubt. Mr. M. meant, âYou know he didnât.â
The otherâs reply was disquieting: âOh, yes, he really did; he really did more than once. Thatâs what put ⦠I mean, he really was a wretchedly unhappy man, he was really in a very tight place, he really was at the end of his tether.â
He paused, and Mr. M. said slowly, âAnd so you â¦?â
The other recovered, âAnd so I was not surprised when the end came.â
âNo,â said Mr. M. âNo, you were not surprised, not a bit surprised. But perhaps you will understand that I am still puzzled?â
Mr. Millum rose. âMr. Mycroft,â he said with perfect courtesy, âI am sure you had every right, on the invitation of the inspector, to act as an additional adviser, and you have every right also to view this house as a possible tenant. I would do anything in my power to aid either the official inquiry or someone who might wish to be a neighbor for the summer. But I think you will understand that I see no use in our getting your two interests confused. The first issue is, as you say, officially closed. It is a
