"My old college chum, Andy Gump — otherwise known as Mr Raddon," said the Saint at once. "So he has got a police record. I thought as much. What do we know about him?"

"Not very much. He's not one of the regulars." Teal consulted his memorandum, although he probably knew it by heart already. "He's only been through our hands once, and that was in 1933.

The detective's jaw dropped.

"Hey, wait a minute!" he yapped. "You can't—"
