"Don't do anything rash," he urged, laying a detaining hand on my arm.
"I quite understand your feelings," he continued, looking at me with his kindly blue eyes. "When I first heard the nature of your errand I felt a good deal embarrassed. But it was then too late. What I knew, I knew. I assure you, Doctor, that what I have heard this morning, far from assisting me to solve the Rosemere mystery, will prove a positive hindrance to my doing so. I shall no longer feel at liberty to employ ruse or strategy in my dealings with the lady, and if I find her shall have to treat her with the utmost consideration."
"Do you think she murdered the man? Is she the woman whose name you promised to reveal next Tuesday?"
"I must decline to answer that question."
I glanced at him for a minute in silence.
"If I am not mistaken, this flight will precipitate matters," he went on, reflectively. "If the right party hears of it, I expect an explosion will follow."
"Don't talk in enigmas, Mr. Merritt; either say what you mean or--" I paused.
"Hold your tongue," he concluded, with a smile. "You are quite right. And as I can't say any more at present, I will say nothing. By the way, I hear Mrs. and Miss Derwent and Mr. Norman are in town."
"Yes," I curtly assented. "Well, Mr. Merritt," I went on, abruptly changing the subject, "I must leave you now. I am very much upset by your attitude towards Mrs. Atkins. I am not yet sure that I shall not tell her husband. Together, we may perhaps prevent her falling into your hands."
The detective smiled indulgently as we parted. I saw now all the harm I had done. Poor Mrs. Atkins had feared from the first that she might be suspected, and having discovered that she was being watched, had naturally been unwilling to leave the protection of her own home. When Argot was arrested she thought all danger was over, till I stupidly blurted out that the detective was stalking a woman, not a man. Then she fled. And she chose the middle of the night, reasoning, no doubt, that at that hour the sleuth would most likely be off his guard. Since I had known her and her husband better, I could no longer suspect her, and I now tried to remember all the arguments Merritt had formerly used to prove her innocence. Foolish she might have been, but criminal, never,--I concluded. And it was I who had put her enemies on her track!
