"My research was made the more interesting by the fact that shortly after I undertook the work for Mr. Glover the subject gave me, voluntarily and quite unsuspectingly, the complete story of his strange adventure at Rest Hollow, an adventure for which he frankly confessed that he could not account. It coincided exactly with the hypothesis which I had established for him; that he had at one period of his life been mentally unbalanced, and that he had in some way re-gained his sanity but not completely his memory. When I knew that there was likely to be a crime attributed to him (for Mr. Glover had hinted as much) my interest doubled. For Mr. Kenwick had on various occasions shown himself possessed of the highest ideals and a fineness of caliber which I have not often encountered. And so, in the employ of Professor Morgan, I shifted the focal point and turned the search-light of science upon the accuser. It has resulted in the most startling revelations."
There was an inarticulate stir in the crowded room. From the rear seats men and women strained forward to catch every word as it fell, clear-cut and decisive, from the scientist's lips. Jarvis sat with one hand thrust into his pocket, and his keen eyes fixed upon the group of lawyers below. A casual observer of the scene might easily have mistaken his position and assigned to him the role of prosecuting attorney.
"There was an insurmountable barrier, of course," he continued, "to my making any personal examination of Mr. Glover, as I had done with the former subject. One man was innocent and unsuspecting; the other, I felt certain, would be on his guard. And he was. Since I left his service, Richard Glover has avoided me. So a more indirect means of accomplishing my task had to be devised. After some consideration I decided to enlist the aid of an ally whom I knew to be both clever and discreet."
A long-drawn sigh swept the court-room. It was that sigh, a mixture of eagerness and satisfaction by means of which an audience at a theater indicates to the actors that the performance is living up to its advertisements.
"Mr. Kenwick himself," the witness went on in his calm, even voice, "had called my attention to a certain Madame Rosalie, a spiritualistic medium, who was taking the city by storm. He had interviewed her for his paper, and from his description I imagined that she might be able and willing to assist me. So I went to see her, and at the first mention of Mr. Kenwick's name she became intensely interested."
