Hammersley watched von Winden as he turned toward Doris with a smile, bowing deeply, his sense of the situation lost for a second in the obligations of civility, as he murmured a phrase of congratulations. “I am much honored by your confidences,” he said formally, “and I deeply regret----” He got no further, for Hammersley had sprung in suddenly toward him, risking Udo’s shot, which was fired quickly, without aim. A furious struggle followed. Hammersley caught at von Winden’s wrist and his weight bore him back against the rock, while both of them fought for the possession of the weapon. The German officer was smaller than his cousin but his wrists were good and he was quicker than Hammersley. They bore only friendship for each other but the incentive of each was greater even than hatred could have been. They struggled in silence, the thought of the possession of the papers uppermost in the minds of both. The struggle was not that of kinsman against kinsman, but of England against Germany. Realizing the desperateness of Hammersley’s attack and the purpose of it, von Winden knew that a victory for Hammersley meant the loss of the papers and so he was bent on killing his cousin if he could, Hammersley on preventing him from doing so. They swayed from side to side, breathing hard, while Doris crouched against the side of the cavern, dumb with terror. Twice she saw the weapon in the German officer’s hand point downward toward Cyril’s back and then, before it could be used, saw Cyril’s arm quickly push it upward. She knew that she was in danger, but she did not know what to do. At one moment von Winden seemed to have the advantage and in another Cyril. Udo’s back was against the wall and one of Cyril’s arms was around him, while their legs were intertwined as each tried to get the other off his balance. Suddenly with an effort Hammersley managed to wrench the pistol from von Winden’s hand and he tossed it into the corner of the cavern. Von Winden had every ethical right to kill Hammersley if he could, but after what his cousin had done for him, Hammersley could not kill Udo. That was impossible. He must succeed without that. This generosity nearly proved fatal to him for the German managed to reach Hammersley’s automatic in his own holster and had almost disengaged it when Hammersley caught his hand again, and the struggle was renewed. But Doris, whose senses and initiative had slowly returned to her, now crept around the walls of the cave and when von Winden’s outstretched hand came within her reach she seized his forearm in both of her hands and clung to it desperately, keeping the muzzle pointed away from Cyril. She was swayed to and fro with the struggling men, who finally toppled sideways and fell to the floor, dragging her with them, but von Winden’s grasp of the weapon, never quite secure, was loosened and, as they dropped, it went flying under the table.
