When a painting vanishes from a maritime museum and a dead body is found nearby, the newly established Lockwood Antique Hunter’s Agency, Freya Lockwood and her Aunt Carole, are called to investigate. Following a lead that takes them aboard a glamorous antiques cruise sailing toward the Red Sea in Jordan, they quickly discover that the ship’s art gallery is filled with stolen antiquities. Each antique is also listed in Freya’s late mentor’s journals that detail unsolved cases. In chasing a murderer with a stolen painting, they may have found something more sinister than they ever could’ve imagined. Their hunt soon turns deadly when they learn that the enigmatic and dangerous art trafficker named The Collector could be on board. Will Freya and Carole be able to discover the Collector’s identity and stop his murderous plans before the ship docks?

Freya Lockwood is shocked when she learns that Arthur Crockleford, an antiques dealer and her estranged mentor, has died under mysterious circumstances. She has spent the last 20 years avoiding her quaint English hometown, but when she receives a letter from Arthur asking her to investigate --- sent just days before his death --- Freya has no choice but to return to a life she had sworn to leave behind. Joining forces with her eccentric Aunt Carole, Freya follows clues and her instincts to an old manor house for an advertised antiques enthusiast’s weekend. But it’s clear to Freya that the antiques are all just poor reproductions and her fellow guests are secretive and menacing. What is going on at this estate, and how was Arthur involved? Can Freya and Carole discover the truth before the killer strikes again?
