For My Darling Wife: In the Event of My Death—

If you are reading this letter, it means you are the proud owner of Tregarrick Rock Hotel.

When Evie Mead’s husband, Robert, suddenly drops dead of a heart attack, a mysterious note is found among his possessions. It indicates that Evie may own the rights to a crumbling Art Deco hotel on Tregarrick Rock, one of the Isles of Scilly, off the coast of Cornwall.

Still grieving, Evie is inclined to leave the matter to the accountant to sort out. Her sister Margot, however, flown in from her glamorous career in LA, has other plans. Envisioning a luxurious weekend getaway, she goes ahead and buys two tickets to Tregarrick.

Once at the hotel—more fixer-upper than spa resort—Evie and Margot attempt to get to the bottom of things. But the foul-tempered hotel owner claims he's never met the late Robert, despite mounting evidence. The rest of the island inhabitants, ranging from an ex-con receptionist to a vicar who communicates with cats, aren't any easier to read.

When a murder occurs at the hotel and then another soon follows, frustration turns to desperation. There’s no getting off the island at high tide. And Evie and Margot, the only current visitors to Tregarrick, are suspects one and two. It falls to them to unravel secrets spanning generations—and several of their own—if they want to make it back alive.
