A luxurious yacht, a gorgeous crew with secrets and rivalries...and murder! I Did Warn Her is a cunning locked room mystery set on a billionaire's yacht, by the author of last year's sensation She Started It.

The Ophelia is your typical billionaire yacht: ridiculously luxurious, owned by a ruthless money man, and staffed by a crew whose only job is to indulge the guests' every wish.

Model-gorgeous Sasha is a last-minute hire for a weeklong Atlantic crossing. She joins fellow stewardesses Jade, Imogen, Euphemia, and Lola. The Ophelia's stewardesses are almost identical--blonde and model-gorgeous--and all were lured to the Ophelia by high wages and a chance to leave their problems behind when they set sail. But despite its sleek opulence, the Ophelia isn't as heavenly as it seems. A stewardess on the previous charter died under mysterious circumstances, the guests' expensive jewelry keeps disappearing, and the crew grows steadily more and more suspicious of one another.

Then the yacht's owner brings aboard his best friend and two more women, also beautiful. Also hiding something.

When a crew member turns up dead after a night of partying, everyone on the yacht is a suspect. Who is the jewel thief? Who is the murderer? What will happen when the lights go out, and the crew and the guests are finally on equal footing?

Endlessly twisty and delightfully voyeuristic, I Did Warn Her is a whodunnit on the high seas, where the dark secrets of the ultra-wealthy have nowhere to hide.
