suburbs on the chance of strangers dropping postal orders into it. Lastly, he was known to be a startling acrobat; despite his huge figure, he could leap like a grasshopper and melt into the tree-tops like a monkey. Hence the great Valentin, when he set out to find Flambeau, was perfectly aware that his adventures would not end when he had found him. But how was he to find him? On this the great Valentin’s ideas were still in process of settlement. There was one thing which Flambeau, with all his dexterity of disguise, could not cover, and that was his singular height. If Valentin’s quick eye had caught a tall apple-woman, a tall grenadier, or even a tolerably tall duchess, he might have arrested them on the spot. But all along his train there was nobody that could be a disguised Flambeau, any more than a cat could be a disguised giraffe. About the people on the boat he had already satisfied himself; and the people picked up at Harwich or on the journey limited themselves with certainty to six. There was a short railway official travelling up to the terminus, three fairly short market gardeners picked up two stations afterwards, one very short widow lady going up from a small Essex town, and a very short Roman Catholic priest going up from a small Essex village. When it came to the last case, Valentin gave it up and almost laughed. The little priest was so much the essence of those Eastern flats; he had a face as round and dull as a Norfolk dumpling; he had eyes as empty as the North Sea; he had several brown paper parcels, which he was quite incapable of collecting. The Eucharistic Congress had doubtless sucked out of their local stagnation many such creatures, blind and helpless, like moles disinterred. Valentin was a sceptic in the severe style of France, and could have no love for priests. But he could have pity for them, and this one might have provoked pity in anybody. He had a large, shabby umbrella, which constantly fell on the floor. He did not seem to know which was the right end of his return ticket. He explained with a moon-calf simplicity to everybody in the carriage that he had to be careful, because he had something made of real silver “with blue stones” in one of his brown-paper parcels. His quaint blending of Essex flatness with saintly simplicity continuously amused the Frenchman till the priest arrived (somehow) at Tottenham with all his parcels, and came back for his umbrella. When he did the last, Valentin even had the good nature to warn him not to take care of the silver by telling everybody about it. But to whomever he talked, Valentin kept his eye open for someone else; he looked out steadily for anyone, rich or poor, male or female, who was well up to six feet; for Flambeau was four inches above it. He alighted at Liverpool Street, however, quite conscientiously secure that he had not missed the criminal so far. He then went to Scotland Yard to regularise his position and arrange for help in case of need; he then lit another cigarette and went for a long stroll in the streets of London. As he was walking in the streets and squares beyond Victoria, he paused suddenly and stood. It was a quaint, quiet square, very typical of London, full of an accidental stillness. The tall, flat houses round looked at once prosperous and uninhabited; the square of shrubbery in the centre looked as...
