"What about gold?" repeated Mr. Staines thoughtfully. "And what did you say?"

"Well, as a matter of fact," explained Tester, "I happen to know this place, living in the neighbourhood, and I used to work here about eight years ago, so I took 'em down to the vault."

"And you stood outside, like a—a——"

"Blinking image!" said the explosive companion.
