Jettison glanced at the ledger and resumed his seat.

“Now, then, Mr. Stebbing, I want you to tell me something very definite,” he said. “It's not so long since this happened, so you'll not have to tag your memory to any great extent. In what form did Collishaw pay that fifty pounds to you?”

“That's easy answered, sir,” said the secretary. “It was in gold. Fifty sovereigns—he had 'em in a bit of a bag.” Jettison reflected on this information for a moment or two. Then he rose.

“Much obliged to you, Mr. Stebbing,” he said. “That's something worth knowing. Now there's something else you can tell me as long as I'm here—though, to be sure, I could save you the trouble by using my own eyes. How many banks are there in this little city of yours?”

“Three,” answered Stebbing promptly. “Old Bank, in Monday Market; Popham & Hargreaves, in the Square; Wrychester Bank, in Spurriergate. That's the lot.”

“Much obliged,” said Jettison. “And—for the present—not a word of what we've talked about. You'll be hearing more—later.”

He went away, memorizing the names of the three banking establishments—ten minutes later he was in the private parlour of the first, in serious conversation with its manager. Here it was necessary to be more secret, and to insist on more secrecy than with the secretary of the Second Friendly, and to produce all his credentials and give all his reasons. But Jettison drew that covert blank, and the next, too, and it was not until he had been closeted for some time with the authorities of the third bank that he got the information he wanted. And when he had got it, he impressed secrecy and silence on his informants in a fashion which showed them that however easy-going his manner might be, he knew his business as thoroughly as they knew theirs.

It was by that time past one o'clock, and Jettison turned into the small hotel at which he had lodged himself. He thought much and gravely while he ate his dinner; he thought still more while he smoked his after-dinner pipe. And his face was still heavy with thought when, at three o'clock, he walked into Mitchington's office and finding the inspector alone shut the door and drew a chair to Mitchington's desk.

“Now then,” he said. “I've had a rare morning's work, and made a discovery, and you and me, my lad, have got to have about as serious a bit of talk as we've had since I came here.”

Mitchington pushed his papers aside and showed his keen attention.
