After the quiet and pastoral solitude of Littlefield London seemed unpleasantly crowded and noisy. The reek of petrol was a poor substitute for the clean country air, and the hoot of innumerable motors and 'buses struck on his ear with new and singularly disagreeable force as he took his way along Piccadilly.

Suddenly a noise considerably louder and more ominous than the rest penetrated his hearing, and looking hastily round he saw that a collision had taken place between a taxi-cab and a motor-van bearing the name of a well-known firm in Oxford Street—with apparently tragic results to the taxi-cab, which lurched in the road like a drunken man vainly attempting to steer a straight course, and eventually toppled half over on to the pavement, where it struck a lamp-post with a terrific crash as it came to rest.

With the rapidity peculiar to the life of cities a crowd instantly began to assemble; and as a burly policeman, notebook in hand, pushed through the people, a middle-aged gentleman stepped, with some difficulty, out of the wrecked cab, and stumbled forward on to the kerb, almost into the arms of Anstice, who reached the spot at the same moment and caught him as he staggered and seemed about to fall.

"Hold up, sir!" Anstice involuntarily gripped the gentleman's shoulder to support him; and his friendly tone and prompt help apparently assured the other man, who pulled himself together pluckily.

"Thanks, thanks!" He was white, and evidently had been somewhat upset, for the taxi had swerved half across the road to the discomfort of its occupant. "You are most kind. I am really not hurt, only a little shaken. The driver of the van was entirely to blame—I hope, constable, you will make all possible inquiries into the matter."

As a first step towards doing so the policeman stolidly requested the speaker's name and address, and these having been furnished he proceeded to interrogate the van-driver and the taxi-man, both of whom were only too ready to pour out voluble explanations, each accusing the other of carelessness with a freedom of language only known, apparently, to those who have intimate acquaintance with the dark ways of motors and their accompanying vices.

In the meantime the middle-aged gentleman turned to Anstice with a word of gratitude for his timely support.

"You're sure you're not hurt?" Anstice thought the other man looked oddly white. "I'm a doctor—and if I can do anything for you——"

"No, I'm really all right, thanks." He relinquished Anstice's arm, which he had been unconsciously holding, and looked round him. "By good luck I'm opposite my club, and if this fellow has finished with me I'll go in and sit down."

The constable intimated that he had no further need of him for the moment; and having asserted his readiness to appear in court in connection with the case he turned back to Anstice.
