"Can't see no street of that name on either side, Mr. Viner," he said. "Have you got it right, sir?" "That's the name given me," answered Viner. He pointed to a policeman slowly patrolling the side walk. "Ask him," he said. "He'll know." The policeman, duly questioned, seemed surprised at first; then recollection evidently awoke in him. "Mirrypoor Street?" he said. "Oh, yes! Second to your left, third to the right--nice sort o' street for a car like yours to go into, too!" Viner overheard this and put his head out of the window. "Why?" he demanded. The policeman, quick to recognize a superior person, touched his helmet and stepped off the curb toward his questioner. "Pretty low quarter down there, sir," he said, with a significant glance in the direction concerned. "If you've business that way, I should advise you to look after yourself--some queer places down those streets, sir." "Thanks," responded Viner with a grim smile. "Go on, driver, as quick as you can, and stop at the corner of the street." The car swung out of Whitechapel Road into a long, dismal street, the shabbiness of which increased the further the main thoroughfare was left behind; and Viner, looking right and left, saw that the small streets running off that which he was traversing were still more dismal, still more shabby. Suddenly the car twisted to the right and stopped, and Viner was aware of a long, narrow street, more gloomy than the rest, wherein various doubtful-looking individuals moved about, and groups of poorly clad children played in the gutters. "All right," he said as he got down from the car, and the chauffeur made a grimace at the unlovely vista. "Look here--I don't want you to wait here. Go back to Whitechapel Road and hang about the end of the street we've just come down. I'll come back there to you." "Not afraid of going down here alone, then, sir?" asked the chauffeur. "It's a bit as that policeman said." "I'm all right," repeated Viner. "You go back and wait. I may be some time. I mayn't be long."
