I was just fitting my key into the door when I noticed a man at my elbow. I had not seen him approach, and the sudden appearance made me start. He was a slim man, with a short brown beard and small, gimlety blue eyes. I recognized him as the occupant of a flat on the top floor, with whom I had passed the time of day on the stairs.
'Can I speak to you?' he said. 'May I come in for a minute?' He was steadying his voice with an effort, and his hand was pawing my arm.
I got my door open and motioned him in. No sooner was he over the threshold than he made a dash for my back room, where I used to smoke and write my letters. Then he bolted back.

A smile flickered over his drawn face. 'I'm not mad—yet. Say, Sir, I've been watching you, and I reckon you're a cool customer. I reckon, too, you're an honest man, and not afraid of playing a bold hand. I'm going to confide in you. I need help worse than any man ever needed it, and I want to know if I can count you in.'
'Get on with your yarn,' I said, 'and I'll tell you.'
He seemed to brace himself for a great effort, and then started on the queerest rigmarole. I didn't get hold of it at first, and I had to stop and ask him questions. But here is the gist of it:
