Used book – Cause for Annabelle, Patricia Cornwell

Kay Scarpetta, promoted to consultant at the Florida National Forensic Academy, finds herself embroiled in a murder case where physical evidence is conflicting but seems to confirm the hypothesis of a killer acting without motive. At the same time, she investigates the strange disappearance of four people in an apparently quiet neighborhood. Meanwhile, Marino discovers the tortured body of a woman in a nearby house… To solve these cases, Kay Scarpetta relies solely on information provided by a psychopath: is it to help her or, on the contrary, to muddy the waters, without reason.
