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.

Windsor Horne Lockwood III - or Win as his few friends call him - doesn't know how his suitcase and his family's stolen painting ended up in this dead man's apartment.
