So every day, as he strolled on his beat, there sidled up to him the meagre form of Spider Buffin. Every day there greeted him the Spider's "Good-morning, Mr. Keating," till the sight of Officer Keating walking solidly along the pavement with Spider Buffin shuffling along at his side, listening with rapt interest to his views on Life and his hints on Deportment, became a familiar spectacle in Clerkenwell.

Mr. Buffin played his part well. In fact, too well. It was on the seventh day that, sidling along in the direction of his favourite place of refreshment, he found himself tapped on the shoulder. At the same moment an arm, linking itself in his, brought him gently to a halt. Beside him were standing two of the most eminent of the great Frith Street Gang, Otto the Sausage and Rabbit Butler. It was the finger of the Rabbit that had tapped his shoulder. The arm tucked in his was the arm of Otto the Sausage.

"Hi, Spider," said Mr. Butler, "Sid wants to see you a minute."

The Spider's legs felt boneless. There was nothing in the words to alarm a man, but his practised ear had seemed to detect a certain unpleasant dryness in the speaker's tone. Sid Marks, the all-powerful leader of the Frith Street Gang, was a youth whose company the Spider had always avoided with some care.

The great Sid, seated in state at a neighbouring hostelry, fixed his visitor with a cold and questioning eye. Mr. Buffin looked nervous and interrogative. Mr. Marks spoke.

"Your pal Keating pinched Porky Binns this mornin'," said Sid.

The Spider's heart turned to water.

"You and that slop," observed Sid dreamily, "have been bloomin' thick these days."

Mr. Buffin did not affect to misunderstand. Sid Marks was looking at him in that nasty way. Otto the Sausage was looking at him in that nasty way. Rabbit Butler was looking at him in that nasty way. This was an occasion where manly frankness was the quality most to be aimed at. To be misunderstood in the circles in which Mr. Buffin moved meant something more than the mere risk of being treated with cold displeasure.
