"Oh, yes! And then everything will be done in a hurry! 'Quick, Mr. Abrahams! I have fallen in love yesterday and I am being married to-morrow.' But it may take months—years—to find and match perfect stones. It can't be done between to-day and to-morrow. Your bride will be married in something ready-made from the jeweller's."

"If three days are enough to choose a wife," said Wimsey, laughing, "one day should surely be enough for a necklace."

"That is the way with Christians," replied the diamond-merchant resignedly. "You are so casual. You do not think of the future. Three days to choose a wife! No wonder the divorce-courts are busy. My son Moses is being married next week. It has been arranged in the family these ten years. Rachel Goldstein, it is. A good girl, and her father is in a very good position. We are all very pleased, I can tell you. Moses is a good son, a very good son, and I am taking him into partnership."

"I congratulate you," said Wimsey heartily. "I hope they will be very happy."

"Thank you, Lord Peter. They will be happy, I am sure. Rachel is a sweet girl and very fond of children. And she is pretty, too. Prettiness is not everything, but it is an advantage for a young man in these days. It is easier for him to behave well to a pretty wife."

"True," said Wimsey. "I will bear it in mind when my time comes. To the health of the happy pair, and may you soon be an ancestor. Talking of ancestors, I've got an old bird here that you may be able to tell me something about."

"Ah, yes! Always delighted to help you in any way, Lord Peter."

"This photograph was taken some thirty years ago, but you may possibly recognise it."

Mr. Abrahams put on a pair of horn-rimmed spectacles, and examined the portrait of Great-Uncle Joseph with serious attention.

"Oh, yes, I know him quite well. What do you want to know about him, eh?" He shot a swift and cautious glance at Wimsey.
