"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."

He turned away down the street—and in spite of his declaration, he felt that this was certainly the most doubtful place he had ever been in. There were evil and sinister faces on the sidewalks; evil and sinister eyes looking out of dirty windows; here and there a silent-footed figure went by him in the gloom of the December day with the soft step of a wild animal; here and there, men leaning against the wall, glared suspiciously at him or fixed rapacious eyes on his good clothes. There were shops in this street such as Viner had never seen the like of—shops wherein coarse, dreadful looking food was exposed for sale; and there were public-houses from which came the odour of cheap gin and bad beer and rank tobacco; an atmosphere of fried fish and something far worse hung heavily above the dirty pavements, and at every step he took Viner asked himself the same question—what on earth could Miss Wickham and Mrs. Killenhall be doing in this wretched neighbourhood?

Suddenly he came to the house he wanted—Number 23. It was just like all the other houses, of sombre grey brick, except for the fact that it looked somewhat cleaner than the rest, was furnished with blinds and curtains, and in the front downstairs window had a lower wire blind, on which was worked in tarnished gilt letters, the word Surgery. On the door was a brass plate, also tarnished, across which ran three lines in black:

"Dr. Martincole.
Attendance: 3 to 6 p. m.
Saturdays. 5 to 9.30 p. m."

Before Viner took the bell in hand, he glanced at the houses which flanked this East-end surgery. One was a poor-looking, meanly equipped chemist's shop; the other a second-hand clothing establishment. And comforting himself with the thought that if need arose the apparently fairly respectable proprietors of these places might reasonably be called upon for assistance, he rang the bell of Number 23 and awaited the opening of the door with considerable curiosity.
