Grant, remembering how grateful one is when some one deliberately attempts to take the black dog from one's back, wondered why it hadn't been the other way about, and Sorrell had murdered Lamont.

Did they ever quarrel?

No, never that she had known of, and she would have known quick enough.

"Well," said Grant at last, "I suppose you have no objections to lending me these snapshots for a day or two?"

"You'll let me have them back safe, will you?" she said. "They're the only ones I have, and I was very fond of both of them."

Grant promised, and put them carefully away in his pocketbook, praying that they were covered with valuable fingerprints.

"You're not going to get them into trouble, are you?" she asked again as he was going. "They never did a wrong thing in their lives."

"Well, if that's so, they're quite safe," Grant said.

He hurried back to Scotland Yard and, while the fingerprints on the photographs were being recorded, heard Williams' report of an unproductive day among the bookmaking offices of London. As soon as the snapshots were again in his possession, he repaired to Laurent's. It was very late and the place was deserted. A solitary waiter was absentmindedly assembling the crumbs from a table, and the air smelt of rich gravy, wine, and cigarette smoke. The distrait minion laid away the crumb-scoop and bent to hear his pleasure with that air of having hoped for nothing, and of having the melancholy pleasure of being right, which a waiter presents to the foolhardy one who attempts to dine when others have finished. As he recognized Grant he reassembled his features in a new combination intended to read, "What a pleasure to serve a favourite customer!" but which in reality was unfortunately clear as "Good heavens, that was a bloomer! It's that pet of Marcel's."

Grant asked after Marcel, and heard that he had that morning departed for France in a hurry. His father had died and he was an only son, and there was, it was understood, a matter of a good business and a vineyard to be settled. Grant was not particularly desolated at the thought of not seeing Marcel again. The manners on which Marcel had always prided himself had left Grant invariably slightly nauseated. He ordered a dish, and asked if Raoul Legarde was on the premises and, if so, would he be allowed to come and speak to him for a moment. Several minutes later, Raoul's tall figure, clad in white linen overall and cap, emerged from the screens by the door and followed the waiter diffidently to Grant's table. He had an air of a shy child going up for a prize which it knows it has earned.
