An unusual serial killer is wreaking havoc in a small corn-growing town in Kansas; he leaves outlandish signatures, such as a mutilated body within a circle of crows on stakes and a ring of broken corn stalks. On his own initiative, Pendergast, no stranger to bizarre murders, shows up to investigate, and the authors make much hay from the contrast between the lean, infinitely refined and impossibly erudite Pendergast, a distinct descendant of Sherlock Holmes, and the down-home milieu he finds himself in. As if to emphasize his ancestry, the authors give Pendergast a Watson here: one Corrie Swanson, a rebellious, pierced and tattooed teenage girl whom he hires as his driver and guide.
