Over 20 years ago, 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 New York’s 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 not only on Patricia’s kidnapping but also on another FBI cold case – with the suitcase and painting both pointing them towards one man.
