Fenton stiffened in instant concern, his lips tightening. He forced himself to remain where he was for a moment longer, however. It was safe to assume the two below would work up to what they were doing gradually and there were things he desperately wanted to know. Under stress of rage they might let something drop--some clue, some pointer, which would enable him to save both Gerstle and Hansen. They must know what had happened to Gerstle. There was another thud, and Hansen's cry of pain was too loud, this time, to permit of further delay. Fenton unholstered his revolver, snapped off the safety catch and was down the companionway and in the cabin so fast the two kidnappers were taken completely by surprise. He gave them no time to recover. The one who had struck Hansen was just raising a reversed automatic for another blow and was facing away from Fenton near the base of the stairs. A sudden tensing of his muscles failed to save him. Just as a glint of awareness flickered at the perimeter of his vision Fenton's fist caught him flush on the jaw, and sent him crashing backwards. He hit the opposite bulkhead, rebounded and sank with a groan to his knees. Fenton moved in close again, and chopped downward on his wrist, sending the gun clattering. It was a needless precaution, for the man was already going limp, and had held fast to the gun in his backward lurch by convulsively contracting his fingers. He collapsed forward on his face and Fenton did not wait to see if he would try to rise again. The danger that his companion would get to the dropped gun first was too urgent. He could have prevented that by putting a bullet in him with his own gun, but he did not want to kill a key accessory in a murder case and he was too excited to be sure of merely splintering the man's kneecap. The weapon had skidded half-way across the cabin, but Fenton raised his right foot and kicked it two yards further a split second before it could pass into dangerous hands again. The second man had dropped on all fours, and his hand hit the deck with a thud when the gun was kicked beyond reach of his fingers. Fenton reversed his own gun and clobbered the unsuccessful weapon snatcher across the back of his skull with a blow that flattened him out almost at his companion's side. The big detective was breathing harshly when he straightened, his face very white and looked with concern at Hansen, who was moaning and slumping a little in a straight-backed chair, with a swelling ugly-looking bruise on his right forehead. One eye was half-closed, and his breathing was harsher than Fenton's. Fenton bent and gripped him firmly by the shoulders, easing him into a less strained position. "Take it easy," he cautioned. "Just lean back and don't try to talk for a minute. You're going to be all right." "Thanks," Hansen muttered, disregarding the advice. "They ... slugged me twice. Felt like the whole top of my head was coming off the second time."
