“He was in the house about half an hour, and I could catch glimpses of him in the windows of the sitting-room, pacing up and down, talking excitedly, and waving his arms. Of her I could see nothing. Presently he emerged, looking even more flurried than before. As he stepped up to the cab, he pulled a gold watch from his pocket and looked at it earnestly, ‘Drive like the devil,’ he shouted, ‘first to Gross & Hankey’s in Regent Street, and then to the Church of St. Monica in the Edgeware Road. Half a guinea if you do it in twenty minutes!’

“Away they went, and I was just wondering whether I should not do well to follow them when up the lane came a neat little landau, the coachman with his coat only half-buttoned, and his tie under his ear, while all the tags of his harness were sticking out of the buckles. It hadn’t pulled up before she shot out of the hall door and into it. I only caught a glimpse of her at the moment, but she was a lovely woman, with a face that a man might die for.

“‘The Church of St. Monica, John,’ she cried, ‘and half a sovereign if you reach it in twenty minutes.’

“This was quite too good to lose, Watson. I was just balancing whether I should run for it, or whether I should perch behind her landau when a cab came through the street. The driver looked twice at such a shabby fare, but I jumped in before he could object. ‘The Church of St. Monica,’ said I, ‘and half a sovereign if you reach it in twenty minutes.’ It was twenty-five minutes to twelve, and of course it was clear enough what was in the wind.

“My cabby drove fast. I don’t think I ever drove faster, but the others were there before us. The cab and the landau with their steaming horses were in front of the door when I arrived. I paid the man and hurried into the church. There was not a soul there save the two whom I had followed and a surpliced clergyman, who seemed to be expostulating with them. They were all three standing in a knot in front of the altar. I lounged up the side aisle like any other idler who has dropped into a church. Suddenly, to my surprise, the three at the altar faced round to me, and Godfrey Norton came running as hard as he could towards me.

“‘Thank God,’ he cried. ‘You’ll do. Come! Come!’

“‘What then?’ I asked.

“‘Come, man, come, only three minutes, or it won’t be legal.’

“I was half-dragged up to the altar, and before I knew where I was I found myself mumbling responses which were whispered in my ear, and vouching for things of which I knew nothing, and generally assisting in the secure tying up of Irene Adler, spinster, to Godfrey Norton, bachelor. It was all done in an instant, and there was the gentleman thanking me on the one side and the lady on the other, while the clergyman beamed on me in front. It was the most preposterous position in which I ever found myself in my life, and it was the thought of it that started me laughing just now. It seems that there had been some informality about their license, that the clergyman absolutely refused to marry them without a witness of some sort, and that my lucky appearance saved the bridegroom from having to sally out into the streets in search of a best man. The bride gave me a sovereign, and I mean to wear it on my watch-chain in memory of the occasion.”

“This is a very unexpected turn of affairs,” said I; “and what then?”
