"Goin' round to see some of the chaps and pass them the time of day, I shouldn't wonder?"
"Um."
"Well, you keep clear of that lot down in Frith Street, young feller. They're no good. And if you get mixed up with them, first thing you know, you'll be in trouble again. And you want to keep out of that now."
"Um."
"If you never get into trouble," said the policeman sententiously, "you'll never have to get out of it."
"Um," said Mr. Buffin. If he had a fault as a conversationalist, it was a certain tendency to monotony, a certain lack of sparkle and variety in his small-talk.
Constable Keating, with a dignified but friendly wave of the hand, as one should say, "You have our leave to depart," went on his way; while Mr. Buffin, raging, shuffled off in the opposite direction, thinking as hard as his limited mental equipment would allow him.
His thoughts, which were many and confused, finally composed themselves into some order. He arrived at a definite conclusion, which was that if the great settlement was to be carried through successfully it must be done when the policeman was off duty. Till then he had pictured himself catching Officer Keating in an unguarded moment on his beat. This, he now saw, was out of the question. On his beat the policeman had no unguarded moments. There was a quiet alertness in his poise, a danger-signal in itself.
There was only one thing for Mr. Buffin to do. Greatly as it would go against the grain, he must foregather with the man, win his confidence, put himself in a position where he would be able to find out what he did with himself when off duty.
The policeman offered no obstacle to the move. A supreme self-confidence was his leading characteristic. Few London policemen are diffident, and Mr. Keating was no exception. It never occurred to him that there could be an ulterior motive behind Mr. Buffin's advances. He regarded Mr. Buffin much as one regards a dog which one has had to chastise. One does not expect the dog to lie in wait and bite. Officer Keating did not expect Mr. Buffin to lie in wait and bite.
