One night, on my way home from the Temple, I saw in the bills of the evening papers the announcement of the arrest of a Labour Member. It was Chapman, sure enough. At first, I feared that he had got himself into serious trouble, and was much relieved to find him in the flat in a state of blazing anger. It seemed that he had found somebody whom he thought was Lumley, for he only knew him from my descriptions. The man was in a shop in Jermyn Street, with a car waiting outside, and Chapman had--politely, as he swore--asked the chauffeur his master's name. The chauffeur had replied abusively, upon which Chapman had hauled him from the driver's seat and shaken him till his teeth rattled. The owner came out, and Chapman was arrested and taken off to the nearest police-court. He had been compelled to apologise and had been fined five pounds and costs. By the mercy of Heaven, the chauffeur's master was a money-lender of evil repute, so the affair did Chapman no harm. But I was forced to talk to him seriously. I knew it was no use explaining that for him to spy on the Power-House was like an elephant stalking a gazelle. The only way was to appeal to his incurable romanticism. "Don't you see," I told him, "that you are playing Lumley's game? He will trap you sooner or later into some escapade which will land you in jail, and where will I be then? That is what he and his friends are out for. We have got to meet cunning with cunning, and lie low till we get our chance." He allowed himself to be convinced, and handed over to me the pistol he had bought, which had been the terror of my life. "All right," he said, "I'll keep quiet. But you promise to let me into the big scrap when it comes off." I promised. Chapman's notion of the grand finale was a Homeric combat in which he would get his fill of fisticuffs. He was an anxiety, but all the same he was an enormous comfort. His imperturbable cheerfulness and his racy talk were the tonics I wanted. He had plenty of wisdom, too. My nerves were getting bad those days, and, whereas I had rarely touched the things before, I now found myself smoking cigarettes from morning till night. I am pretty abstemious, as you know, but I discovered, to my horror, that I was drinking far too many whiskeys-and-sodas. Chapman knocked me off all that and got me back to a pipe and a modest nightcap.
