Mr. Mori Yada, apparently as cool and unconcerned as ever, presently tripped down the steps of the police-station and went leisurely off, swinging his neatly rolled umbrella. As long as he was within sight of the police-station windows he kept up the same gentle pace—but as soon as he had turned the first corner his steps were quickened, and he made for a spot to which Melky had expected him to make—a cab-rank, on which two or three taxi-cabs were drawn up. He had reached the first, and was addressing the driver, when Melky, who had kept a few yards in the rear, stole gently up to his side and tapped him on the shoulder.

"Mister!" said Melky. "A word—in private!"

Yada turned on his interrupter with the swiftness of a snake, and for a second his white teeth showed themselves in an unmistakable snarl, and a savage gleam came into his dark eyes. Both snarl and gleam passed as quickly as they had come, and the next instant he was smiling—as blandly as ever.

"Oh, yes!" he said. "It is you—how do you do? Perhaps you are going my way—I can give you a lift—Yes?"

Melky drew his man away a yard or two, and lowered his voice to a whisper.

"Mister!" he said, with a note of deep confidence which made Yada look at him with a sudden sense of fear. "Mister!—I wouldn't go no way at all if I was you—just now. You're in danger, mister—you shoved your head into the lions' den when you walked in where I've just seen you! Deep, deep is them fellows, mister!—they're having you on toast. I know where you're thinking of going, mister, in that cab. Don't go—take my tip!"

"How do you know where I'm going?" demanded Yada.

"I was looking over Levendale's shoulder when he wrote that bit of a cheque, mister," answered Melky, in his quietest accents. "You're off to his bank to turn it into cash. And—if you walk into that bank—well, you'll never walk out again, alone! Mister!—they're going to collar you there—there's a trap laid for you!"

Melky was watching Yada's face out of his own eye-corners, and he saw the olive-tinted skin pale a little, and the crafty eyes contract. And on the instant he pursued his tactics and his advantage. He had purposely steered the Japanese into a more crowded part of the street, and now he edged him into a bye-alley which led to a rookery of narrow bye-streets beyond. He felt that Yada was yielding—oppressed by a fear of the unknown. But suddenly Yada paused—drawing back from the hand which Melky had kept on his arm.

"What are you after?" he demanded. "What is your game, eh? You think to alarm me!—what do you want?"
