"'You can get a doctor nearer than me. I'm waiting for a woman case and may be sent for any minute. Try the Dispensary on Canal Street; they've always a doctor there.' "'No--we don't want no Dispensary sharp. We want you. Pal's sent me for you--he knows you, but you mightn't remember him.' "'I'll go.' These are the people I can never refuse. They are on the hunted side of life and don't have many friends. I slipped on my rubbers and coat, picked up my umbrella and my bag with my instruments in it; hung a card in the window so the hall-light would strike it, marked 'Back in an hour'--in case the woman sent for me; locked my door and started after him. "It was an awful night. The streets were running rivers, the wind rattling the shutters and flattening the umbrellas of everybody who tried to carry one--one of those storms that drives straight at the front of the house, drenching it from chimney to sidewalk. We waited under the gas-lamp, boarded a Sixth Avenue car, and got out at a signal from my companion. During the trip he sat in the far corner of the car, his hat slouched over his eyes, his coat-collar covering his ears. He evidently did not want to be recognized. "If you know the neighborhood about Washington Street you know it's the last resort of the hunted. When they want to hide, they burrow under one of these rookeries. That's where the police look for them, only they've got so many holes they can't stop them all. Captain Packett of the Ninth Precinct told me the other day that he'd rather hunt a rattlesnake in a tiger's cage than go open-handed into some of the rookeries around Washington Street. I am never afraid in these places; a doctor's like a Sister of Charity or a hospital nurse--they're safe anywhere. I don't believe that other fellow would have stolen my watch if he had known I was a doctor. "When we left the car at Canal Street, my companion whispered to me to follow him, no matter where he went. We kept along close to the houses, past the dives--the streets, even here, were almost deserted; then I saw him drop down a cellarway. I followed, through long passages, up a creaking pair of stairs, along a deserted corridor--only one gas-jet burning--up a second flight of stairs and into an empty room, the door of which he opened with a key which he held in his hand. He waited until I passed in, locked the door behind us, felt his way to a window, the glow of some lights in the tenements opposite giving the only light in the room, and raised the sash. Then down a fire-escape, across a wooden bridge, which was evidently used to connect the two buildings; through an open door, and up another stairs. At the end of this last corridor my companion pushed open a door. "'Here's the "Doc,"' I heard him say.
