(Formerly published as GIRL WITH THE ORIGAMI BUTTERFLY)_ After years as a homicide investigator in a big city, Detective Sidney Becker accepts the position of police chief in her hometown—a peaceful mountain community in Oregon. Life is good. Beautiful scenery. Low crime. Close to family. Then a woman is found brutally murdered in the woods. The staging of the body resembles a victim found in the same area years earlier. The case went cold. Now the killer has come out of hiding. The only clue found at the crime scene is an origami butterfly with a handwritten verse inside. Sidney finds she is pitted against a killer more cunning than any she has faced before. She must decode his cryptic message and lure him into the open—before he strikes again.
