The detective's suspicion was certainly a startling one, and of course accounted for his anxiety that Dick should in future remain in utter ignorance of our actions. When Boyd had gone he at once commenced to question me upon what theories he had expressed, and in what direction he was prosecuting inquiries. Although I would not allow myself to suspect my best friend, I nevertheless preserved the silence which Boyd had imposed upon me, evading giving him direct answers, preserving the secret of the identity of the man seen in St. James's Park, and managing to put aside his questions by a declaration that personally I was sick of the whole matter, for I felt that it would now ever remain a mystery. That night, however, I remained awake many hours thinking fondly of Eva, and calmly revolving in my mind all that had fallen from the lips of Boyd. He, one of the most skilful officers in London, had formed no theory. He only entertained certain suspicions, vague perhaps, yet by no means groundless. I had not seen Eva since that day when the strange, incomprehensible attempt had been made to take my life, and a strong desire again possessed me to stroll at her side, to hear her voice, to hold her hand. Was it, I wondered time after time, that hand, so soft, slim and delicate, that had actually attempted to secretly take my life? The detective had calmly reviewed all the facts I had explained, and, as a professional investigator of crime, had openly expressed a suspicion in the affirmative. Often had I wondered what kind of woman was Eva's mother, whom I had never met. That she was somewhat eccentric was evident from her daughter's words on the last occasion I had visited Riverdene. I lay there thinking of Eva, scouting every suspicion which the detective's words had aroused within me, until with the first streak of dawn I fell asleep and dreamed of her. Next afternoon, without mentioning anything to Dick save the sending of a telegram to say I should not dine at home, I left my office half an hour earlier, and full of conflicting thoughts travelled down to Riverdene. Having been informed by the servant that Mrs. Blain and Miss Mary were absent in London shopping, but that Miss Glaslyn was at home, I was shown into the long, pleasant drawing-room which opened upon the wide lawn sloping to the river's brink. The great bowls of cut flowers diffused a pleasant odour, and the books and papers lying in the cosy-corner, with its soft cushions of pale-blue silk, betrayed signs of recent occupation. It was a low-ceilinged, comfortable apartment, cool and restful after the dust and glare of the white road outside. In a few moments the door opened and Eva entered, fresh and charming in a cool dress of cream flannel, her sweet face illumined by a smile of glad welcome.
