"Don't let Mr. Boyne know that I've stayed here to-night, auntie," she said, getting up hurriedly. "I'll get away before he comes down. I don't want him to know I've been so ill."

The old woman read her lips and nodded, saying in a whisper:

"As soon as you're gone, dear, I'll make the bed."

"I don't want any breakfast. I'll get to the City early, and have it there."

And this she did.

When Boyne came down to breakfast he asked his housekeeper how her niece was, to which she replied that she had recovered at about ten o'clock on the previous night and gone home to Wimbledon.

Saturday was always an "off" day with Mr. Boyne. Working people did not pay their weekly insurance premiums till Monday. Saturday is the half-day with the working class as Wednesday is with the shop-keeping community. Now on that particular Saturday Bernard Boyne, at eleven o'clock in the forenoon, sent Mrs. Felmore to King Street to buy him a tin of tomato soup. He wrote down the brand on an old envelope. And he wanted nothing else.

"If one grocer has not got it, another has, no doubt. If you can't get it in Hammersmith go down to Chiswick or Bedford Park," he said. "You'll find it somewhere."

And the old woman, whose shopping successes were always marvellous considering her stone deafness, went forth, little dreaming that such a brand as that he had written down was non-existent.

So all the morning until well into the afternoon Bernard Boyne had the house entirely to himself. As soon as she had gone, Boyne put on his white disguise and, rushing upstairs to the locked room, opened it.
