As far as I know, no electrons had darted in either direction when I first laid eyes on Priscilla Eads, nor had I felt faint or dizzy at any point during my association with her, but the fact remains that I have never had swifter or stronger hunches than the two that were connected with her. Monday evening, before Helmar had said much more than twenty words about his missing ward, I had said to myself, "She's upstairs," and knew it. Tuesday morning, when I saw Inspector Cramer of Manhattan Homicide on the stoop, I said to myself, "She's dead," and knew it.
