A blissful setting. A dream life. The perfect murder.

When a beautiful married socialite vanishes from her husband’s luxury yacht, Detective Inspector Robbie Chilcott must find her—dead or alive.

Fearing the worst, Chilcott focuses on the victim’s eccentric yet evasive husband, who maintains his wife isn’t missing at all—she’s simply visiting family.

Chilcott doesn’t buy it.

But with no body and little evidence, proving murder is another matter entirely.

Then alarming news from France flips the investigation on its head and forces Chilcott to view the married couple in an entirely new light.

Suddenly, a luxurious life on the ocean waves isn’t all caviar and Champagne parties. Chilcott is diving headlong into a clandestine world of secrets and lies, lust and deceit.

As the web of treachery darkens, can Chilcott untangle the façade before the vows of love become a prelude to the perfect crime?
