“At the registry office in Henrietta Street.”

“The mouse-trap,” said I.

“No; the registry office,” she replied.

“And when’s it to be?” I asked.

“My next evening after this.”

Well, it came to that next evening. I got permission from a firm of book-buyers to occupy a window opposite. And there I observed that little parlour tragedy which you can see in the corner of any old wainscotted room if only you keep quiet long enough.

It did not happen successfully that first time. For half an hour he walked her up and down Henrietta Street. I saw my publisher come out of his door, little dreaming of the comedy that was being played as he passed them by. And every time they stopped outside the Registry Office windows, she stood and read the notices of soldiers deserted the army, of children that were lost, while he talked of the great things that life was offering to them both just inside those varnished doors.

After a time they walked away and I came out from my hiding-place. Something must have upset her, I thought, and I went across to look at the notices in the window. There was nothing to frighten her there; yet she had scampered away home to that little hole in Clapham, and there vanished out of sight.

But it came at last. It came the very next of her short evenings. I was on the lookout again. I saw them march up to the door. No hesitation this time. He must have been eloquent indeed to have led her so surely as that.

I saw him lift the spring of the trap. I saw her enter with tip-toe steps, but more full of confidence now. Then I heard the sharp snap of the door as it fell.
