Nick heard him coming, but did not have time to extricate himself from Grantley’s dogged grasp. He raised his weapon, though, and was about to fire at Willard, when he saw that the latter was directly between him and Helga Lund. Under the circumstances, the detective did not dare to fire for fear of hitting the actress. He kept Grantley down as best he could with his left hand, and waited for Willard with his right hand still extended, holding the automatic. He might have an opportunity to fire, but, if not, he could at least partially ward off the expected blow from the chair. Just as Willard paused and swung the chair aloft, Grantley managed partially to dislodge the detective, with the result that Nick was obliged to lower his right arm quickly. Otherwise he would undoubtedly have lost his balance completely, and the surgeon-convict would have had the upper hand in another second or two. This involuntary lowering of Nick’s guard served the purpose that Grantley had intended. Willard’s cumbersome weapon descended with uninterrupted force on the detective’s shoulders and the back of his head. Nick lowered the latter instinctively, and thus saved himself the worst of the blow. Nevertheless, the impact of the chair was stunning in its force. The detective felt his senses reeling, but he somehow managed to retain them and to grasp the chair, which he blindly wrenched from Willard’s grasp. As he did so, however, Grantley succeeded in throwing him off and scrambling to his feet. Nick followed his example almost simultaneously, dropped his revolver into his pocket--for fear it would fall into the hands of one of his enemies--and, grasping the heavy chair with both hands, whirled it about his head. His two antagonists dodged it hurriedly, thus clearing a space about him. Their blood was up, however--especially Grantley’s--and they felt sure that the detective had by no means recovered from the blow. “Catch the chair, Willard!” cried Grantley. The younger physician obeyed instantly, grasping the round of the chair with both hands, and thus preventing Nick from using it to any advantage. The detective shoved it forward into the pit of Willard’s stomach, but the newcomer managed to retain his hold. He guessed that Grantley merely meant him to keep Nick busy in front, in order to allow of a rear attack; and such was the case. While the detective was occupied with Willard, Grantley stole behind him and plunged his hand into Nick’s pocket, in search of the automatic. The detective was obliged to let go of the chair and clamp his hand on Grantley’s wrist. He was still feeling very groggy as a result of the punishment he had recently received, and a thrill of apprehension went through him. Grantley’s hand was already deep in his pocket, grasping the butt of the weapon; and there was nothing about the wrist hold to prevent the criminal from turning the muzzle of the automatic toward his side and pulling the trigger.
