The train dashed across the bridge, sparks grinding from its wheels. When it stopped, panting sullenly, the two men sprang aboard.
Garth flattened himself against the side of the car and watched them reappear, leading a third who wore a grey mask above a plain brown suit. He heard a croaking, unnatural voice issue from behind the mask.
"Didn't look for you so soon, friends."
Excitement drove the melancholy from Garth's brain. The undertaking had begun reassuringly. Simmons had no suspicion that he was in the hands of the police. Garth noticed also as he entered the car that the passengers were not aware of the substitution. He resented the repugnance in the glances they turned on the mask. Simmons' attitude toward life became comprehensible. But, as the journey extended itself interminably, Garth grew restless. He realized he was in the position of a man entering a cavern without a light. He must feel his way step by step. He must walk blindly toward innumerable and fatal pitfalls.
At last the train paused for the change from locomotive to electric motor. Although he knew that normally no passengers would board it at this place, he gazed anxiously from the window. A man stood close to the track with the evident intention of entering the train. Garth saw him elude a brakeman, saw him grasp the railing and swing himself out of sight. A moment later the man walked into the car, stopped dead, and turned sharp, inquisitive eyes on the gray mask.
About the figure was a somber air, accentuated by a black felt hat, drawn low over the eyes. It let Garth see, however, a sharp and colorless face which conveyed an impression of uncommon forcefulness.
After a moment the slender man leaned over and spoke with a leer.
"You must be a star gambler, judging from your face."
He continued to stare as though expectant of an answer. Perhaps some countersign was demanded. If that was so the whole enterprise swayed in the balance. Garth concentrated his thoughts with difficulty. One word had strayed circuitously from the gang to him. He used it at random, trying to approximate the voice he had heard at the bridge.
"That depends on whether I hold the ace."
