The wizened face of the older man was molded in intent lines of complement of two hundred and twenty men were present—except Comerford's crew was marooned on an islet, about a square mile in area Comerford the day before she sailed from Norfolk. With him came a boatload of scientific apparatus and whose mind had been turned by the horror that had come to his country under the domination of the Nazi if this might have been the source of Androka's zone of silence, when like a stinging wet lash. Overhead, the sky was a storm-racked mass of clouds, broken in one spot by a tiny patch of starlit blue. fumbling at the neck of his slicker. Rain was coursing down his white cheeks, streaking them with glistening furrows. The fellow was a headache to Curtis. He was overfriendly with a black-browed bos'n's mate named Joe Bradford—the worst trouble maker his taut face, restless, searching eyes, and eternally nervous manner oilskins, blinking his eyes against the yellow light. hard on his latest invention to pull Hitler's teeth and re-establish the Czech Republic!" Comerford ever since the navy department had sent the scientist on board the cruiser to carry on his "As if by providence, sir, there's a clear patch. I'm wondering—" His underlined heavily. "Here's what I make it," the commander told his navigating officer. "Bet you're not off appreciably." "Your secrecy might well cost the United States navy one of its best light cruisers—and us our lives!" he said angrily. "We need that check by radio at once! If you're not talking nonsense, call off your dogs till we learn just where we are!" Comerford . Station 297 calling U. S. Cruiser Comerford —" "U. S. Cruiser Comerford calling Station 297!" the operator intoned, winking at the two officers over Androka's discomfiture, and asked for Cruiser Comerford !" Curtis sighed with relief. He saw that Nelson was staring fiercely Comerford calling Station 364. U. S. Cruiser Comerford calling Station 364—" Comerford . Bearings north west by three west.

Put them together, and they will defeat the Nazi hordes which have ravaged my country!" Curtis was a little shocked by the hatred that gleamed in Androka's eyes, under their bushy brows. There was something of the wild animal I'm afraid we're gored!" "Get out the collision mat!" Curtis ordered. "We ought to be able to keep her up!" enveloped the entire cruiser. Looking over the side, he could no longer Comerford was shrouded in a huge pall of yellowish-gray mist, and more of it was coming up from below—from ventilators and hatchways and skylights—as if the whole ship were flooded with some evil vapor. fallen before the early Nazi blitzkrieg, when their defenders found themselves struck numb and helpless by a gas that had been flooded into The vapor clouds that enveloped the Comerford were becoming thicker. All about the deck lay the forms of unconscious seamen, suddenly stricken helpless. And then Curtis saw other forms flitting about the deck—forms that looked like creatures from another world, but he recognized them for what they were—men wearing gas masks. Nelson was nowhere in sight. The steersman lay in a limp heap beside the swinging wheel. Then a gas-masked figure appeared through the shroud of mist and steadied it, so that the cruiser would not be was completely walled in by the yellowish-gray mist. He felt his senses Two words, in particular, registered clearly on his mind. One was a cloud seemed to be mounting within him until The rain had abated to a foggy drizzle. The wash of the surf swung the Comerford in a lazy, rolling motion, as she lay with her bow nosing into the sandbar at the entrance of the inlet. From her bridge, Navigating Officer Nelson watched the gas-masked figures moving about the decks, descending companionways—like goblins from an ancient fairy tale or a modern horror story. Nelson looked like a goblin himself, with his face covered by a respirator. At his side, stood his fellow conspirator Bos'n's Mate Joe Bradford, also wearing a gas mask. Comerford's crew were being carried to the lowered accommodation ladder and transferred into waiting lifeboats. before the ship's rid of that damn gas!" Bradford shook his head in disagreement. "The old geezer claims he's got a neutralizing chemical in one of them tanks of his that'll clear Maginot Line," Bradford reminded him. "It saved a lot of lives for the Fuehrer —lives that'd have been lost if the forts had to be taken by our storm troopers!" Nelson grunted and turned away. A short, thick-set figure in the uniform of a German naval commander had ascended the accommodation World War, he wouldn't have lost his business my mother would still be living. When he joined the Nazi party, the way became clear to use Comerford ?" Brandt nodded his square head. "We have a full crew—two hundred Comerford's unconscious crew and row them ashore. with strange-looking radio equipment, and more gas tanks like those Androka had brought aboard the Comerford with him, and dynamos and batteries that looked like something out of a scientific nightmare. Comerford and ve have another invention of Androka's vich vill be even more useful vhen ve come to cut the out of her convoy." "The Carethusia "What's the idea?" "Her cargo," Brandt explained. "It iss more precious than rubies. It includes a large shipment of boarts." barrels of lard oil for machine-tool lubrication. Our agents have been watching the convoys closely for weeks for just such a cargo as the Carethusia is taking over." "The gestapo takes care of Czechs and Poles and Frenchmen and other misfires, if there is the slightest suspicion of treachery on his part, Comerford . The masked German seamen were installing some sort of apparatus up there—a strange-looking object that looked something like an that portholes were being opened, and men were spraying chemical around to rid the below-decks atmosphere of the lethal gas that had overcome the Comerford's American crew. Returning to the bridge, he found that the tide in the inlet had risen out his hand. "Congratulations, Herr Kommander Nelson!" he said. "Ve have stolen one of the United States navy's newest and fastest cruisers!" He made a gesture as if raising a beer stein to drink a toast. " Prosit! Stars were twinkling in a patch of black-blue sky, and broken mountains as if a wave of searing heat had scorched them. According to his last calculations, the Comerford had been cruising off the Maine coast. This probably was one of the islets of that All around him in the nearly total darkness, he could make out the dim "A bit of a headache from the gas, but that's all. Any orders, sir?" which smelled strongly of treachery and sabotage. Comerford had been deliberately steered to this place puzzle—Androka's zone of silence
