eyebrows. âWhat on earth made him do that, sir?â
âI imagine that it was partly remorse and partly because he considered it to be the best way out. If he hadnât committed suicide he would have been arrested and tried for treason.â
âTreason!â
âI am afraid that is the only word one can use.â The speaker paused. âIt was a bad business in every way. Medlicot was a bit of a genius in his own line, and for nearly a year before he died he had been conducting experimental work on some new gadget in connection with submarines. There is no need to enter into further details at the moment. All that matters is that the invention panned out very satisfactorily, and we were just congratulating ourselves that we were one up on the Boche when we learned through an agent that a complete copy of the plans had been sent over to Berlin, and that our Nazi friends were already hard at work on them. As you can well believe, this was something of a facer.â
Owen moistened his lips. âYou mean that Medlicot had sold them?â
âThere was no other conceivable explanation. Only four people had the necessary knowledge, and three of them were men whom it would be quite ridiculous to suspect. BesidesââGreystoke gave the faintest possible shrugââwe have a written confession which settles the matter beyond question. He must have posted it just before he shot himself.â
âIt seems unbelievable.â Owen sat for an instant staring silently at his companion. âI ran across Medlicot once at Harwich, and he struck me as being a thoroughly decent fellow. What made him do such a damnable thing?â
âAh! Now we are coming to the point. You know your way about the West End, Bradwell. I donât want you to think that I have been delving impertinently into your private affairs, but I am informed that you are one of those fortunate mortals who are not entirely dependent on their pay, and that when you have a spot of leave you generally put in a day or two in Town. Is that correct?â
Owen nodded. âMy father left me quite comfortably off, sir, and I have a good many friends in London. I like to look them up every now and then.â
âQuite so. Ever heard of a man named Mark Craig?â
âMark Craig? Sounds vaguely familiar, but I canât place him at the moment.â
âHe runs a club in Grosvenor Streetâvery posh, expensive place where a crowd of rich people go to play poker. Itâs called the Mayflower.â
âOh, yes, I remember now, sir. I have never been there myself, but I have met blokes who belong to it.â
âYou have met one, anyhow. Medlicot was a member. If he hadnât enjoyed that distinction he would probably be alive now.â
âYou mean he had been losing money there, sir?â
âQuite a lot, I imagine. We have no actual proof of that, but everything seems to point to it. I fancy that he was being threatened with exposure, and that in a moment of desperation he sold those plans in order to settle up his debts.â
âBut couldnât you find out for certain?â
âNot so easy, Bradwell. We did our utmost, of course, but in a case of suicide people are uncommonly shy about giving anything away. Donât want to be dragged into a scandal.â
âWasnât there an official inquiry?â
âA very private one. You see, the mischief was done, and there was no sense in advertising the fact to the whole world. Besides, we had grounds for suspecting a certain highly placed gentleman at the German Embassy. If his name had cropped up the fat would have been in the fire. Our ingenuous government still seem to be under the illusion that they can scrape through without going to war, and to bring a charge of that nature against a prominent Hun diplomat without cast-iron evidence to back it upâwell, the mere suggestion would be sufficient to throw the whole
