Over twenty years ago, the heiress Patricia Lockwood was abducted during a robbery of her family's estate, then locked inside an isolated cabin for months. Patricia escaped, but so did her captors - and the items stolen from her family were never recovered. Until now. On the Upper West Side, a recluse is found murdered in his penthouse apartment, alongside two objects of note: a stolen Vermeer painting and a leather suitcase bearing the initials WHL3. For the first time in years, the authorities have a lead - with the suitcase and painting both pointing them toward one man.

But then something from his own past, a past he doesn't even remember, comes back to visit terror upon him and his family.
