When a bibliophile is murdered, it takes a bookseller to solve the crime. Good Advice, New Mexico, is a sunny town with a gloomy bookshop. The store's eerie corridors are the province of Avery Sharecross, an ex-cop who has made the transition from chasing killers to tracking rare books. One afternoon, the local sheriff interrupts his book club meeting, and Sharecross's old career collides with his new one. The area's premier book collector has been found bludgeoned to death on the floor of his family library. A fifth-generation resident of Good Advice, Lloyd Fister devoted his life to books, accumulating a collection of local history that date backs to the sixteenth century. In his library, a single volume is missing: a Spanish book with a sinister past. Is the missing volume a clue, a motive, or a murder weapon? It will take a collector's eye to decide.
