"Flicked out through a pigeonhole. That's what took practice, to make 'em fall just right. Also the cigar."

"And the odor of tobacco?"

He got a little vial out of his pocket, uncorked it, and again I caught the sweet and heavy odor of Peter Magnus' cigar.

"An' here's a fine point I'm proud of," said Jemmy. "I had this made from half a dozen of Magnus' cigars I found in a box in his room. So the smell was just right. I thought for a while of showin' some smoke, but didn't dare risk it."

"But the note," I said. "That was the cleverest of all."

Jemmy chuckled and glanced at Godfrey.

"You'll understand that, Jim," he said. "You remember I worked it backward in that National City Bank case."

Godfrey nodded.

"I remember the signature disappeared from old Murgatroyd's check."

"Backward or forward, it don't make no difference. It all depends on the acid."
