"Stay with me!" Joan's eyes were dilated, and she caught Harrison's arm with hands that shook violently. "We can defend these rooms! While one sleeps the other can watch! Do not call the police; their blunders would doom us. You have worked in the quarter for years, and are worth more than the whole police force. The mysterious instincts that are a part of my Eastern heritage are alert to danger. I feel peril for us both, near, creeping closer, gliding around us like serpents in the darkness!"
"But I can't stay here," he scowled worriedly. "We can't barricade ourselves and wait for them to starve us out. I've got to hit back—find out who's behind all this. The best defense is a good offense. But I can't leave you here unguarded, either. Damn!" He clenched his big fists and shook his head like a baffled bull in his perplexity.
"There is one man in the city besides yourself I could trust," she said suddenly. "One worth more than all the police. With him guarding me I could sleep safely."
"Who is he?"
"Khoda Khan."
"That fellow? Why, I thought he'd skipped months ago."
"No; he's been hiding in Levant Street."
"But he's a confounded killer himself!"
"No, he isn't; not according to his standards, which means as much to him as yours do to you. He's an Afghan who was raised in a code of blood-feud and vengeance. He's as honorable according to his creed of life as you or I. And he's my friend. He'd die for me."
"I reckon that means you've been hiding him from the law," said Harrison with a searching glance which she did not seek to evade. He made no further comment. River Street is not South Park Avenue. Harrison's own methods were not always orthodox, but they generally got results.
"Can you reach him?" he asked abruptly. She nodded.
"Alright. Call him and tell him to beat it up here. Tell him he won't be molested by the police, and after the brawl's over, he can go back into hiding. But after that it's open season if I catch him. Use your phone. Wire may be tapped, but we'll have to take the chance. I'll go downstairs and use the booth in the office. Lock the door, and don't open it to anybody until I get back."
When the bolts clicked behind him, Harrison turned down the corridor toward the stairs. The apartment house boasted no elevator. He watched all sides warily as he went. A peculiarity of architecture had, indeed, practically isolated that wing. The wall opposite Joan's doors was blank. The only way to reach the other suites on that floor was to descend the stair and ascend another on the other side of the building.
As he reached the stair he swore softly; his heel had crunched a small vial on the first step. With some vague suspicion of a planted poison trap he stooped and gingerly investigated the splintered bits and the spilled contents. There was a small pool of colorless liquid which gave off a pungent, musky odor, but there seemed nothing lethal about it.
"Some damned Oriental perfume Joan dropped, I reckon," he decided. He descended the twisting stair without further delay and was presently in the booth in the office which opened on the street; a sleepy clerk dozed behind the desk.
Harrison got the chief of police on the wire and began abruptly.
"Say, Hoolihan, you remember that Afghan, Khoda Khan, who knifed a Chinaman about three months ago? Yes, that's the one. Well, listen: I'm using him on a job for a while, so tell your men to lay off, if they see him. Pass the word along
He hung up the receiver, thought vigorously for a few minutes, and then dialed another number that was definitely not related to the police station. In place of the chief's booming voice there sounded at the other end of the wire a squeaky whine framed in the argot of the underworld.
"Listen, Johnny," said Harrison with his customary abruptness, "you told me you thought you had a lead on the Kossova murder. What about it?"
"It wasn't no lie, boss!" The voice at the other end trembled with excitement. "I got a tip, and it's big!—
"I'll be there in an hour," promised the detective. He left the booth and glanced briefly out into the street. It was a misty night, as so many River Street nights are. Traffic was only a dim echo from some distant, busier section. Drifting fog dimmed the street lamps, shrouding the forms of occasional passers-by. The stage was set for murder; it only awaited the appearance of the actors in the dark drama.
