I had to leave it behind, for I couldn’t leave any clues to breed suspicions. The gentry who are after me are pretty bright-eyed citizens. You’ll have to take me on trust for the night, and tomorrow you’ll get proof of the corpse business right enough.’

I thought for an instant or two. ‘Right. I’ll trust you for the night. I’ll lock you into this room and keep the key. Just one word, Mr Scudder. I believe you’re straight, but if so be you are not I should warn you that I’m a handy man with a gun.’

‘Sure,’ he said, jumping up with some briskness. ‘I haven’t the privilege of your name, Sir, but let me tell you that you’re a white man. I’ll thank you to lend me a razor.’

I took him into my bedroom and turned him loose. In half an hour’s time a figure came out that I scarcely recognized. Only his gimlety, hungry eyes were the same. He was shaved clean, his hair was parted in the middle, and he had cut his eyebrows. Further, he carried himself as if he had been drilled, and was the very model, even to the brown complexion, of some British officer who had had a long spell in India. He had a monocle, too, which he stuck in his eye, and every trace of the American had gone out of his speech.

‘My hat! Mr Scudder—’ I stammered.

‘Not Mr Scudder,’ he corrected; ‘Captain Theophilus Digby, of the 40th Gurkhas, presently home on leave. I’ll thank you to remember that, Sir.’

I made him up a bed in my smoking-room and sought my own couch, more cheerful than I had been for the past month. Things did happen occasionally, even in this God-forgotten metropolis.

I woke next morning to hear my man, Paddock, making the deuce of a row at the smoking-room door. Paddock was a fellow I had done a good turn to out on the Selakwe, and I had inspanned him as my servant as soon as I got to England. He had about as much gift of the gab as a hippopotamus, and was not a great hand at valeting, but I knew I could count on his loyalty.

‘Stop that row, Paddock,’ I said. ‘There’s a friend of mine, Captain—Captain’ (I couldn’t remember the name) ‘dossing down in there. Get breakfast for two and then come and speak to me.’

I told Paddock a fine story about how my friend was a great swell, with his nerves pretty bad from overwork, who wanted absolute rest and stillness. Nobody had got to know he was here, or he would be besieged by communications from the India Office and the Prime Minister and his cure would be ruined. I am bound to say Scudder played up splendidly when he came to breakfast. He fixed Paddock with his eyeglass, just like a British officer, asked him about the Boer War, and slung out at me a lot of stuff about imaginary pals. Paddock couldn’t learn to call me ‘Sir’, but he ‘sirred’ Scudder as if his life depended on it.

I left him with the newspaper and a box of cigars, and went down to the City till luncheon. When I got back the lift-man had an important face.

‘Nawsty business ‘ere this morning, Sir. Gent in No. 15 been and shot ‘isself. They’ve just took ‘im to the mortiary. The police are up there now.’

I ascended to No.
