“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.”

He fixed a time for me to call again upon him the next day, when Mrs. O'Kelly would be away from home. He instructed me to walk quietly up and down on the opposite side of the road with my eye on the attic window, and not to come across unless he waved a handkerchief.

Rising to go, I thanked him for his kindness. “Don't put it that way, me dear Paul,” he answered. “If I don't get ye out of this scrape I shall never forgive meself. If we damned silly fools don't help one another,” he added, with his pleasant laugh, “who is to help us?”

We crept downstairs as we had crept up. As we reached the first floor, the drawing-room door suddenly opened.

“William!” cried a sharp voice.

“Me dear,” answered the O'Kelly, snatching his pipe from his mouth and thrusting it, still alight, into his trousers pocket. I made the rest of the descent by myself, and slipping out, closed the door behind me as noiselessly as possible.
