But Grace was no fool. He’d got a resourceful and a bold mind. He was determined and inventive. Look at his handling of poor old Markins. Without a doubt he guessed that Markins was watching him and, with a flourish, struck first. You’ve got to admire his cheek. Of course it was Grace himself who was abroad on the night when Markins heard something in the passage. Again, he coolly nipped in the complaint to his aunt that Markins was up to no good and she ought to get rid of him. But he reckoned without his Flossie. Flossie didn’t behave according to pattern. The woman who emerged from our postmortem was nothing if not shrewd. Even Terence Lynne, whose opinion, poor girl, was distorted by jealousy, admitted her astuteness. I fancy Mrs Rubrick was brisk enough to have her doubts about Douglas Grace. His popularity waned after their quarrel over Markins and again, since they were bound to tell me of this, Grace got in first with his version. It is in his under-estimation of Florence Rubrick that we see, for the first time, that brittle, cast-iron habit of thinking that his earlier German training probably bred in him. He was one of the clutch of young foreign Herrenvolk, small, thank God, but infernal, who did their worst to raise Cain when they returned, bloated with Fascism, to their own countries.

At this point, Br’er Fox, you’ll raise your eyebrows and begin to look puffy. You will say that so far I’ve presented a very scrubby case against this young man. I agree. If he had come to trial we’d have been on tenterhooks, but as you have seen by the report, Grace did not come to trial.

It was with the object of forcing an exposure that I laid for him. I let him know that I proposed to hunt for the candle which Albert Black threw into the pens. This evidently shook Master Douglas. We’ve found the candle and it has got his prints, but of course they wouldn’t have been conclusive evidence. However, he’d probably decided I was a nuisance on general grounds, and that my liquidation would be to the greater glory of the Fatherland.

When I said I’d go to the annexe for my cigarette case, he made one of his snap decisions. He would follow me, get the branding iron from the wool-shed, apply the proved method, and send me down country with the crutchings. Losse, wearing my overcoat, came in for the cosh.
