ON A DEPRESSING November afternoon, when the street lights scarce sufficed to pierce the wet mist, a young policeman stood at his post in Baker Street at the point where Crawford Street joins the main thoroughfare. Moisture dripped from his helmet and glistened on his waterproof cape; the stream of traffic had splashed him with mud to the knees. People have been heard to wonder what passes through the minds of policemen during their long hours of point duty when they gaze on the stream of traffic with the detachment of a cow looking at a passing train. Are there human emotions behind those impassive features? Do they ever unbend?<br />In the case of young P.C. Richardson, posted in Baker Street that November afternoon, we are in a position to answer these questions. Newly posted to the D Division of the Metropolitan Police after a strenuous course of training at Peel House, he was not ruminating upon the frailty of human nature or regretting the change from his native Arbroath to a section house in central London. He was wondering how he could win admission to the Criminal Investigation Department where, as he knew, hours were long, meals irregular, failures frequent, and pay but little higher than he was receiving while in uniform; but the work was varied, interesting, and sometimes exciting, and hard work was what he wanted.
