The more Nick thought about it the more certain he became that the latter supposition was nearer the truth than the former. Grantley had caused Helga Lund to break down completely before one of the most important and critical audiences that had ever been assembled in New York, to be sure, but, with a man of his type, was that likely to be anything more than the first step?
He had threatened to ruin her career, and he was nothing if not thorough in whatever he attempted. Therefore—so Nick reasoned—further trouble might be looked for in that quarter.
The thought was an unwelcome one. The detective had taken every practicable precaution to shield Helga from further molestation, but he knew only too well that Grantley’s attacks were of a sort which usually defied ordinary safeguards.
The possibility of new danger to the actress spurred Nick on to added concentration.
Assuming that Grantley was still in New York, in disguise, and bent upon inflicting additional injury on the woman he had once loved, where would he be likely to hide himself, and what would be the probable nature of his next move?
The detective answered his last question first, after much weighing of possibilities.
Grantley was one of the most dangerous of criminals, simply because his methods were about as far removed as possible from the ordinary methods of criminals. He had confined himself, thus far, to crimes in which he had made use of his immense scientific knowledge, surgical and hypnotic.
Accordingly, the chances were that he would work along one of those two lines in the future, or else along some other, in which his special knowledge would be the determining factor.
Moreover, since his escape, he had repeatedly called his mastery of hypnotism to his aid. That being so, Nick was inclined to believe that he would continue to use it, especially since Helga had shown herself so susceptible to hypnotic influence.
Could the detective guard against that?
