“I wouldn’t say that. You remember I thought General Blaker was poisoned. He was mixed up with Asiatics too. There were queer circumstances about the death of that Greek millionaire in Rome two years ago. The world’s old and men have been poisoning each other for five thousand years and science only began to look into it yesterday. There’s a lot of drugs in the world that you can’t buy at the chemist’s.”

“Good Gad,” Lomas protested, “we’re in Scotland Yard, not the Arabian Nights. What you mean is you can’t do anything?”

“Even so. Can you? Who wanted him dead?”

“Nobody but a lunatic. He had no money to leave. He was on the best terms with his son. He was a popular old boy, never had an enemy. He had no secrets—most respectable—lived all his life in public.”

“And yet his son snatched at his keys before he was cold. And his dear old friend Osbert knew of his death before he was dead and made a bee-line for his papers. By the way, what was in his papers?”

Lomas shrugged. “Our fellows are working at ’em.”

“And who is Osbert?”

“Well, you know, he’s coming to see me. He put in his protest to the Commissioner, and they were going to turn him down, of course. But I thought I’d like to listen to Colonel Osbert.”

“Me too,” said Reggie.

“By all means, my dear fellow. But he seems quite genuine. He is the executor. He is an old friend, about the oldest living. Not a spot on his record. Long Indian service.”
