Garth saw her shoulders commence to shake. This emotion fired a tiny hope, yet it angered him that she should suffer, too.

"Stop that," he said roughly. "It isn't worth it to you. I'm sorry I spoke. I ought to have had better sense, but I'm going out of town to-day on a job--"

He paused. He turned back to the window.

"That's why I spoke, because--because I may be away a very long time."

She controlled herself.

"How long, Jim?"

"G.o.d knows."

"Where? West?"

He shook his head.

"Up the state. It's just as well now. I've got to go. I ought to be getting ready."

She arose. She spoke wistfully.

"Then good-by, Jim. And you'll try to understand? Maybe you'll come to see me just the same when you get back?"

He swallowed hard, forcing back his craving for abandonment, for revelation.

"When I get back," he said.

CHAPTER II

IT OPENS NORA'S EYES

Garth waited at the end of the bridge above Garrison. At eight o'clock it was dark, but the river, gla.s.s-like between the rugged hills, retained a pallid light. At a short distance two men smoked and chatted.

They had withdrawn themselves in response to Garth's moodiness. He fancied they discussed him as one already dead.

A whistle shrieked. The hills rumbled. Flinging their cigars in the water, the men rejoined Garth. He slipped the mask from his pocket, and secreted his features behind its gray protection.

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 rea.s.suringly. Simmons had no suspicion that he was in the hands of the police. Garth noticed also as he entered the car that the pa.s.sengers were not aware of the subst.i.tution. He resented the repugnance in the glances they turned on the mask. Simmons' att.i.tude 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 pa.s.sengers 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."

The slender man continued to stare. Garth's heart sank, but at last the other straightened with a nod.

"Suppose you take a little stroll with me."

Garth arose and followed him down the aisle. He didn't know whether to interpret that quick command as acceptance or condemnation. He might be going to the work for which he had been chosen, or--and he realized how likely that was--to an execution. Yet he had no alternative. He must follow the slender, sinister figure into dark places not knowing.

They paused on the platform. Garth thought it likely that one of the inspector's men was in the car, but of course the fellow would not confess himself by stepping to the vestibule at their heels. It would be enough for him to know that they were on board and that the train was not scheduled to stop before reaching the Grand Central Station.

Garth knew that, too. Therefore he could not understand why his conductor stooped and with an air of confidence opened the vestibule door and raised the trap. Garth started, for, as if the engineer were an accomplice and had received some subtle signal, the brakes commenced to grind while the train lost its speed rapidly.

The slender man grasped Garth's arm, and, as the train stopped, leapt with him to the right of way and hurried him into the shadows at the foot of the embankment. Any men the inspector might have had on the train had been outwitted.

He saw ahead the red and green lights of an open draw-bridge. He understood now, and marvelled at the simplicity of the trick. Certainly it would not have occurred to the inspector to post his men at the Harlem River where express trains were seldom detained at night. Yet it had been only necessary to send some small boat to loiter in the draw at the proper moment to a.s.sure the security of the conspirators.

Immediately Garth lost all sense of direction. The other led a stealthy, circular course through a lumber yard, across a fence, around darkened buildings, and finally onto a small wharf. A craft was moored there--a barge, Garth thought at first. It lay in darkness except for its navigating lights, and, as Garth looked, even these were extinguished.

The slender man glided across the wharf, and, Garth at his heels, stepped to the deck. There he reached over the railing, dropping something from his hand. Garth heard three splashes at regular intervals. A blade of light flashed sharply athwart the darkness and became an open doorway, framing a troubled face.

Garth, shoved from behind, stumbled over the sill into the presence of five men who circled about him, like cats, wary and suspicious. He would know now. One word from his conductor would deliver him to the inevitable judgment of that circle.

But the slender man slipped in after him, closing the door.

"The cops are drunk with sleep," he said.

Garth breathed again. But into that moment's respite crept the thought of Nora, suddenly become un.o.btainable. Resolutely he fought his depression back. At a gesture from the slender man he sat on a bench against the wall.

He saw now that the apparent barge was a rough houseboat, unpainted, unfinished, with windows closed and heavily barred. The only furniture was this bench and another opposite with a deal table between. Fumes of gasoline and cylinder oil came through an open doorway forward and mixed repellently with an atmosphere already poisoned by tobacco. For all five smoked, not with enjoyment, Garth noticed--rather in an abandonment to nerves. It impressed him that these men, who unquestionably were the cleverest and most indomitable of the Hennion group, should expose this restlessness, this apparent fear, on the threshold of the night's work.

His conductor, indeed, was the only one immune to the contagion of suspense.

Garth glanced at these others with a sharp personal curiosity. They varied amazingly from his antic.i.p.ation. One, a sallow youth with untidy yellow hair and large-rimmed eye-gla.s.ses, might have been a student of the most devoted species. Another cunningly resembled a well-to-do business man, while a third had the clothing and the air of a tramp.

The fourth, with his dapper tailoring and ferret-like face, was more familiar to the expert in crime.

These, however, Garth pa.s.sed over quickly for the fifth, perhaps because, with the detective's extra sense, he foresaw there a special and unintelligible menace.

This man brought his huge, handsome figure forward and leaned heavily on the table. His close-cropped hair, dampened by the heat, curled about a bronzed forehead from beneath which inquisitorial and threatening eyes challenged.
