Sometimes called "the American Sherlock Holmes," Professor Craig Kennedy is a scientist detective based at Columbia University, where he applies his extensive knowledge of chemistry and psychology to the mysteries that come his way, and utilizes such cutting-edge devices as lie detectors and portable seismographs. Kennedy appears in eighteen detective novels, and in The Soul Scar, he may be up against his most perplexing case yet--trying to unravel a murder mystery through the analysis of a beautiful woman's dreams.
