The thing wouldn't have happened if any other constable than Collins had been put on point duty at Blackfriars Bridge that morning. For Collins was young, good-looking, and knew it. Nature had gifted him with a susceptible heart and a fond eye for the beauties of femininity. So when he looked round and saw the woman threading her way through the maze of vehicles at "Dead Man's Corner," with her skirt held up just enough to show two twinkling little feet in French shoes, and over them a graceful, willowy figure, and over that an enchanting, if rather too highly tinted, face, with almond eyes and a fluff of shining hair under the screen of a big Parisian hat-that did for him on the spot. He saw at a glance that she was French-exceedingly French-and he preferred English beauty, as a rule. But, French or English, beauty is beauty, and here undeniably was a perfect type, so he unhesitatingly sprang to her assistance and piloted her safely to the kerb, revelling in her voluble thanks and tingling as she clung timidly but rather firmly to him.
