Isaac Bell sprinted the distance that separated them.

He moved in utter silence.

So intent were the three that the first they knew of the tall detective’s approach was the crack of a powerful right fist knocking the nearest man to the deck. Bell wheeled on the balls of his feet and launched a left-hand haymaker with all his weight and strength behind it. Had it landed, he would have evened the odds at one to one.

Bell’s target moved with superhuman speed. He slipped the punch so it missed his head and smashed his shoulder. It still connected with sufficient power to drive the man to the deck. But he was carrying a heavy rope looped over his shoulder, and the springy Manila coils absorbed the shock.

A counterpunch exploded from the dark with the concentrated violence of a pile driver. Isaac Bell rolled with it, sloughing off some of the impact, but the momentum pinwheeled him into the railing and so far over it that he found himself gazing down at the motorboat pressed against the hull directly under him. The man who had unleashed the blow that sent Isaac Bell flying dragged his two victims to the rail. At a grunted command, his accomplice jumped over the body of their fallen comrade and charged Bell to finish him off.

Bell saw a knife flash in the light from the library.

He twisted off the rail, regained his feet, and tried to sidestep a vicious thrust. The blade passed an inch from his face. Bell kicked hard. His boot landed solidly. The man hit the railing and tumbled over it. A shriek of pain and fear ended abruptly with the sickening thud of his body smashing on the motor-boat sixty feet below.

The boat sped away with a roar of throttles opened wide.

Isaac Bell whipped a Browning automatic from his coat.

“Elevate!” he commanded the astonishingly quick and powerful man with the rope, whom he could see only as a shadow. “Hands in the air.”

But again the leader of the attack moved like lightning. He threw the coiled rope. Loops of it entangled Bell’s gun hand. In the instant it took to untangle himself, Bell was astonished to see the attacker scoop his unconscious accomplice off the deck and throw him over the railing into the sea. Then he ran.

Bell threw off the rope and leveled his pistol: “Halt!”

The attacker kept running.

Isaac Bell waited coolly for him to reach the light spill from the library in order to get a clear shot to shoot the man’s legs out from under him. His highly accurate Browning No. 2 semi-automatic firing .380 caliber cartridges could not miss. Just before reaching the lights, the running man clapped both hands on the rail, flipped high in the air like a circus acrobat, and tumbled into the dark.

Bell ran to the spot the man had jumped from and looked over the side of the ship.

The water was black, bearded white where the Mauretania’s hull raced through. Bell could not see whether the man was swimming or had sunk beneath the waves. In either event, unless the motorboat returned and its crew was extraordinarily lucky in their search, it was highly unlikely they would pull him out before the bitter-cold Irish Sea sucked the life from his body.
