‘That’s all right,’ he said. ‘I’ve been keeping an eye on the business round the corner, and she ain’t interested when I’M round this end.’

‘You seem mighty interested in the business,’ I said.

‘Yes,’ said Jack. ‘This sort of thing just suits a man of my rank in times of peace.’

‘What made you think of the window?’ I asked.

‘Oh, that’s as simple as striking matches. I’m up to all those dodges. Why, where there wasn’t a window, I’ve fixed up a piece of looking-glass to see if a girl was taking any notice of me when she thought I wasn’t looking.’

He went away, and presently Mary was at the window again, and this time she had a tray with cups of tea and a plate of cake and bread-and-butter. I was prizing off the strips that held the sash, very carefully, and my heart suddenly commenced to gallop, without any reference to me. I’d never felt like that before, except once or twice. It was just as if I’d swallowed some clockwork arrangement, unconsciously, and it had started to go, without warning. I reckon it was all on account of that blarsted Jack working me up. He had a quiet way of working you up to a thing, that made you want to hit him sometimes—after you’d made an ass of yourself.

I didn’t hear Mary at first. I hoped Jack would come round and help me out of the fix, but he didn’t.

‘Mr—Mr Wilson!’ said Mary. She had a sweet voice.

I turned round.

‘I thought you and Mr Barnes might like a cup of tea.’
