Careless in Red by Elizabeth George
Blurb from George's site:
"Lynley discovers the body of a young man who appears to have fallen to his death. The closest town, better known for its tourists and its surfing than its intrigue, seems an unlikely place for murder. However, it soon becomes apparent that a clever killer is indeed at work, and this time Lynley is not a detective but a witness and possibly a suspect."
Phantom Prey by John Sandford
From the summary on Sandford's site:
"A widow comes home to her large house in a wealthy, exclusive suburb to find blood on the walls, no body – and her college-age daughter missing. She's always known that her daughter ran with a bad bunch. What did she call them – Goths?...
But the police can't find the girl, alive or dead, and the widow truly panics. There's someone she knows, a surgeon named Weather Davenport, whose husband is a big deal with the police, and she implores Weather to get her husband directly involved. Lucas gets in only reluctantly – but then when a second Goth is slashed to death in Minneapolis, he starts working it hard. The clues don't seem to add up, though. And then there's the young Goth who keeps appearing and disappearing: Who is she? Where does she come from and, more important, where does she vanish to?"
