He remembered that he had promised, despite the lateness of the hour, to telephone the lad directly he had received a certain report, and to tell him whether he might wait up for his return or whether he must turn in. Kerry, stamping his small, neatly shod feet upon the pavement, smiled agreeably. He was thinking of the telephone which recently he had had installed in his house in Brixton. His wife had demanded this as a Christmas box, pointing out how many uneasy hours she would be spared by the installation. Kerry had consented cheerfully enough, for was he not shortly to be promoted to the exalted post of a superintendent of the Criminal Investigation Department?

These reflections were cheering and warming; and, waiting until a gap occurred in the stream of cabs and cars, he crossed Piccadilly and proceeded along Bond Street, swinging his shoulders in a manner which would have enabled any constable in the force to recognize “Red Kerry” at a hundred yards.

The fierce eyes scrutinized the occupants of all the lighted cars. At pedestrians also he stared curiously, and at another smaller group of travellers waiting for the buses on the left-hand side of the street he looked hard and long. He pursued his way, acknowledged the salutation of a porter who stood outside the entrance to the Embassy Club, and proceeded, glancing about him right and left and with some evident and definite purpose.

A constable standing at the corner of Conduit Street touched his helmet as Kerry passed and the light of an arc-lamp revealed the fierce red face. The Chief Inspector stopped, turned, and:

“What the devil's the idea?” he demanded.

He snapped out the words in such fashion that the unfortunate constable almost believed he could see sparks in the misty air.

“I'm sorry, sir, but recognizing you suddenly like, I——”

“You did?” the fierce voice interrupted. “How long in the force?”

“Six months, sir.”

“Never salute an officer in plain clothes.”
