Brilliant psychiatrist Doctor Carter Cole often investigates crimes that seem to be supernatural in nature. Using his medical training to discern the mental states of suspects he interrogates, making deductions based on the quirks manifest in their behavior, and is aided in his cases by identical-twin nurses. Written by Frederick C. Davis, this edition collects the first half of the series: "The Case of the Crimson Claws," "The Case of the Skinned Men," "The Case of the Crazy Witness," "The Case of the Silent Giantess," and "The Case of the Queen's Headsman."
