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 assure 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 unobtainable. 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 anticipation. One, a sallow youth with untidy yellow hair and large-rimmed eye-glasses, 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 passed 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.
The slender man, who clearly was the leader, crossed the room.
"Seeing ghosts, George?" he asked. "Or maybe you're anxious for a glimpse of what Simmons hasn't got any more. Why not show him the big event, Simmons?"
His laugh, scarcely audible, was like the wrath of a gigantic sneer.
Garth's hand crept to his pocket and closed over his revolver. George drew back.
"Look yourself, Slim, and it ought to be done."
The other swung on him angrily.
"Do you think I'm bringing him here without checking him up. He doesn't have to take his mask off to show you a scar. The lot of you look like sudden wealth for a nerve specialist. Sit down. We'll get to business."
He swung on Simmons.
"I know how you feel about that. Now, listen. All you know is that we wanted a scientific fellow who doesn't use his profession exclusively for the benefit of humanity. Also one without any nerves. I've always heard that of you."
Garth nodded, smiling a little to himself. Lack of nerves had been the inspector's chief requisite. Now the criminals demanded the same quality. He stood, as it were, between two deadly fires. He wondered if murder was on the boards. He recalled the slip of white paper in his pocket, questioning if he would be able to finger it, to scratch upon it those vital invisible directions before these sharp and overcurious eyes.
The slender man hurried on, glancing at his watch.
"We're waiting for one more. At first all you have to do is to keep close to George. We're going to crack a safe."
His voice colored apologetically.
"No jewelry or bags of gold. George falls for that cheap stuff now and then, but you needn't be ashamed of this job, Simmons. By the way, I don't have to ask you if you duck your lid every time the band blats 'Oh, say, can you see!'"
Garth shook his head.
"Say, Simmons," George broke in, "you talk yourself to death. That explosion must have hurt your voice something fierce."
Again Garth tried to approximate the croaking tone he had heard at the bridge.
"Talk's as cheap and easy as cracking safes."
He risked it for its effect on the others. Moreover it was an antidote for his nervous strain to give that much rein to the antagonism he already experienced for the huge, dark fellow.
Secretive laughter greeted his daring. A gesture from the leader halted George's movement, almost instinctive, to resent the affront physically. Then three faint and regular splashes came from the water.
They all held their poses of the moment statuesquely until, at a nod from the leader, the intellectual-looking youth arose and moved towards the door.
During that moment of waiting Garth tried to fashion what he knew into a recognizable pattern, but the pieces were incomplete. He could only wonder why they had sent to Chicago for an anarchistic chemist to connive with this expert at a task as simple as cracking a safe.
The youth turned the lock and opened the door a little. It was pushed boisterously against him, and, beyond his amazed back,
