Isaac Bell looked up at the open overhang that extended from the bridge, expecting the Mauretania’s answering flash. But the bridge wing was deserted of officers and seamen, and no one signaled back. He saw no response either from the foremast that towered invisibly two hundred feet into the dark sky. The lookout perched in his crow’s nest watched ahead of the ship, not to the side where the Aldis lamp had aimed its narrow beam.

Suddenly Bell saw the splash of a bow wave. It gleamed white, in sharp contrast to the black water. Then he saw the boat itself veering close. It was a Wolseley-Siddeley, burying its nose in the steep seas, hurling spray, and tearing ahead in the hands of a helmsman who knew his business. It drew alongside directly under him, forty feet long, sharp as a knife, spewing a bright feather of propeller wash.

Bell heard a shout behind him, a frightened cry stifled abruptly. He whirled around and scanned the dark boat deck. Then he heard a grunt of pain and a sudden rush of feet.

From the companionway where he had said good night to Archie burst a tight knot of men in fierce struggle. Their silhouettes lurched past the light spilling from the First Class library windows. Three big men were forcing two smaller fellows to the rail. Bell heard another shout, a cry for help, a hard blow, a muffled groan. A victim doubled over, clutching his stomach, the wind knocked out of him.

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.

Bell holstered his pistol and buttoned his coat over it. What he had just seen was singular in his experience. What would possess the man to throw his unconscious accomplice overboard to certain death, then hurl himself to the same fate?

“Thank you, sir, thank you so very much,” spoke a voice in the accent and baroque cadence of a cultured Viennese. “Surely we owe our lives to your swift and courageous action.”

Bell peered down at a compact shadow. Another voice, a voice that sounded American, groaned, “Wish you’d saved us before he socked me in the breadbasket. Feels like I got run over by a streetcar.”

“Are you all right, Clyde?” asked the Viennese.

“Nothing a month of nursing by a qualified blonde won’t cure.” Clyde climbed unsteadily to his feet. “Thanks, mister. You saved our bacon.”

Isaac Bell asked, “Were they trying to kill you or kidnap you?”

“Kidnap.”

“Why?”

“That’s a long story.”

“I’ve got all night,” said Isaac Bell in a tone that demanded answers. “Did you know those men?”

“By their actions and their reputation,” said the Viennese. “But thanks to you, sir, we were never formally introduced.”

Gripping each man firmly by the arm, Bell walked them inside the ship and back to the smoking room, sat them in adjoining armchairs, and took a good look at their faces. The American was young, a tousle-headed, mustachioed dandy in his early twenties who was going to wake up with a black eye as well as a sore belly.

The Viennese was middle-aged, a kindly-looking, dignified gentleman with pink-tinted pince-nez eyeglasses that had stayed miraculously clipped to his nose, a high forehead and intelligent eyes. His suit of clothes was of good quality. He wore a dark necktie and a round-collar shirt. In contrast to his sober outfit, he had an elaborate mustache that curled up at the tips. Bell pegged him for an academic, which proved to be not far off. He, too, was going to have a shiner. And blood was oozing from a split lip.

“We should not be here,” the Viennese said, gazing in wonder at the richly carved wood paneling and elaborate plaster ceiling of the enormous lounge, which was decorated in the manner of the Italian Renaissance. “This is the First Class smoking room. We voyage in Second Class.”

“You’re my guests,” Bell said tersely. “What was all that about?”

The smoking room steward appeared, cast a chilly eye on the Second Class passengers, and told Bell as solicitously as such an announcement could be uttered that the bar was closed.

“I want towels and ice for these gentlemen’s bruises,” Isaac Bell said, “an immediate visit from the ship’s surgeon, and stiff scotch whiskeys all around. We’ll start with the whiskeys, please. Bring the bottle.”

“No need, no need.”

The American concurred hastily. “We’re fine, mister. You’ve gone to plenty trouble already. We oughta just go to bed.”

“My name is Bell. Isaac Bell. What are yours?”

“Forgive my ill manners,” said the Viennese, bowing and pawing at his vest with shaking fingers, muttering distractedly, “I appear to have lost my cards in the struggle.” He stopped searching and said, “I am Beiderbecke, Professor Franz Bismark Beiderbecke.”

Beiderbecke offered his hand, and Bell took it.

“May I present my young associate, Clyde Lynds?”
