It was certainly mysterious, and my whole mind was centred upon the affair that day.

As I stood before my glass at seven o'clock that evening, I presented a strange, uncanny figure, dressed as I was in a shabby suit which I had obtained during the day from a theatrical costumier's in Covent Garden.

Haines, to whom I had invented a story that I was about to play a practical joke, stood by much amused at my appearance.

"Well, sir," he exclaimed; "you look just like a bricklayer's labourer!"

The faded suit, frayed at the wrists and elbows, had once been grey, but it was now patched, brown, smeared with plaster, and ingrained with white dust, as was the ragged cap; while the trousers were ragged at the knees and bottoms. Around my neck was a dirty white scarf and in my hand I carried a tin tea-bottle as though I had just returned from work.

"Yes," I remarked, regarding myself critically. "Not even Miss Shand would recognise me—eh, Haines?"

"No, sir. I'm sure she wouldn't. But you'll have to dirty your face and hands a bit. Your hands will give you away if you're not careful."

"Yes. I can't wear gloves, can I?" I remarked.

Thereupon, I went to the grate and succeeded in rubbing ashes over my hands and applying some of it to my cheeks—hardly a pleasant face powder, I can assure you.

At a quarter to eight, with the precious letter in the pocket of my ragged jacket, I left Albemarle Street and sauntered along Piccadilly towards the Circus. The rain had ceased, but it was wet underfoot, and the motor buses plashed foot passengers from head to foot with liquid mud. In my walk I passed, outside the Piccadilly Hotel, two men I knew. One of them looked me straight in the face but failed to recognise me.
