A stunning wedding in a country house hotel. Fourteen guests. One killer.

Rina’s friend Bridie Duggan is tying the knot — at her dream venue. Milbourn House is a secluded island hotel, built on a network of twisty tunnels. Rina rows out for the ceremony, along with a handful of other guests.

But one of them has murder in mind . . .

The next day, Rina’s out exploring when a piercing scream tears through the calm. Rina races down the twisty steps to shore — to find a dead body!

This guest didn’t fall to their death.
They were pushed.

A storm is rolling in on Bridie’s perfect day. Now there’s no way on or off the island.

Rina can’t just stand by and wait for the police. Not when there’s a killer lurking in the dark tunnels beneath their feet.
