The O'Kelly's address was in Belsize Square. I was about to ring and knock, as requested by a highly-polished brass plate, when I became aware of pieces of small coal falling about me on the doorstep. Looking up, I perceived the O'Kelly leaning out of an attic window. From signs I gathered I was to retire from the doorstep and wait. In a few minutes the door opened and his hand beckoned me to enter.

“Walk quietly,” he whispered; and on tip-toe we climbed up to the attic from where had fallen the coal. “I've been waiting for ye,” explained the O'Kelly, speaking low. “Me wife—a good woman, Paul; sure, a better woman never lived; ye'll like her when ye know her, later on—she might not care about ye're calling. She'd want to know where I met ye, and—ye understand? Besides,” added the O'Kelly, “we can smoke up here;” and seating himself where he could keep an eye upon the door, near to a small cupboard out of which he produced a pipe still alight, the O'Kelly prepared himself to listen.

I told him briefly the reason of my visit.

“It was my fault, Paul,” he was good enough to say; “my fault entirely. Between ourselves, it was a damned silly idea, that party, the whole thing altogether. Don't ye think so?”

I replied that I was naturally prejudiced against it myself.

“Most unfortunate for me,” continued the O'Kelly; “I know that. Me cabman took me to Hammersmith instead of Hampstead; said I told him Hammersmith. Didn't get home here till three o'clock in the morning. Most unfortunate—under the circumstances.”

I could quite imagine it.

“But I'm glad ye've come,” said the O'Kelly. “I had a notion ye did something foolish that evening, but I couldn't remember precisely what. It's been worrying me.”

“It's been worrying me also, I can assure you,” I told him; and I gave him an account of my Wednesday evening's experience.

“I'll go round to-morrow morning,” he said, “and see one or two people. It's not a bad idea, that of Jarman's. I think I may be able to arrange something for ye.”
