Faintly the whirring of a motor reached them. George sprang for the door. Slim motioned Garth ahead and followed him to the sidewalk where an automobile had drawn up. It exposed, in the vague light, an air of smug respectability in itself protective.
The driver wore a fur coat with a voluminous cape, of a common chauffeur pattern. Its collar was turned up so that it completely hid the lower part of the wearer's face. Garth didn't understand at first when Slim took a smaller coat from the car, stooped, and whispered in the driver's ear. The other stepped obediently to the sidewalk, removed his great coat, handed it to Slim, and slipped on the smaller one. Slim motioned George and Garth into the car, followed them, and, while he jerked out his instructions, drew down the side curtains. Garth was to sit on the back seat with George, who would keep one hand conveniently on his automatic. Slim would be opposite, his gun handy, and the bottle of acid ready at his side.
"And that isn't all," he leered. "You're too precious to take chances with. Here! Lean forward."
He flung the chauffeur's great coat across Garth's shoulders, and, over his chained wrists, buttoned it tight about him. He chuckled as the car started.
"The cape, George, makes it look as if our friend kept his hands out of sight for warmth. Let's hope the train'll be a little chilly, too. Your arms are going to sleep and get a nice rest, Garth."
He chuckled again. He took his own handkerchief and borrowed George's. With the two he improvised a gag which he fastened skillfully in the prisoner's mouth. Then he turned the great collar up so that the gag was hidden.
"You've a swell chance to make trouble now, Garth. That's how I check up on a bull's promises. If anybody tries to stop us or to snitch you free you'll get the acid in those shining peepers without being able to move. You'd better pray everybody keeps straight."
Enough light entered from the front to draw an ashen glow from the acid which he held at his side perpetually ready.
Beyond the driver's back Garth could follow their route among tortuous downtown thoroughfares into lower Broadway. They went then at a discreet pace straight through the heart of the city. He watched the lights flash by, the impatient traffic, the crowds, hurrying and voluble. Such things, taken with the grim man opposite and his unique threat, became like one of those dreams which project against a familiar background incredible and grotesque details.
The car at last drew a hollow response from the pavement of the Broadway bridge. Slim moved restlessly.
