He began to explain with feverish eagerness.

"Strike me, Sid," he stammered, "it ain't like that. It's all right.
Blimey, you don't fink I'm a nark?"

Mr. Marks chewed a straw in silence.

"I'm layin' for him, Sid," babbled Mr. Buffin. "That's true. Strike me if it ain't. I'm just tryin' to find out where he goes when he's off duty. He pinched me, so I'm layin' for him."

Mr. Marks perpended. Rabbit Butler respectfully gave it as his opinion that it would be well to put Mr. Buffin through it. There was nothing like being on the safe side. By putting Mr. Buffin through it, argued Rabbit Butler, they would stand to win either way. If he had "smitched" to Officer Keating about Porky Binns he would deserve it. If he had not—well, it would prevent him doing so on some future occasion. Play for safety, was Mr. Butler's advice, seconded by Otto the Sausage. Mr. Buffin, pale to the lips, thought he had never met two more unpleasant persons.

The Great Sid, having chewed his straw for a while in silence, delivered judgment. The prisoner should have the benefit of the doubt this time. His story, however unplausible, might possibly be true. Officer Keating undoubtedly had pinched him. That was in his favour.

"You can hop it this time," he said, "but if you ever do start smitchin', Spider, yer knows what'll happen."

Mr. Buffin withdrew, quaking.

Matters had now come to a head. Unless he very speedily gave proof of his pure and noble intentions, life would become extremely unsafe for him. He must act at once. The thought of what would happen should another of the Frith Streeters be pinched before he, Mr. Buffin, could prove himself innocent of the crime of friendliness with Officer Keating, turned him cold.

Fate played into his hands. On the very next morning Mr. Keating, all unsuspecting, asked him to go to his home with a message for his wife.
