2:32 p.m. Wealthy, privileged Ilaria Cavendish checks into a luxury London hotel and orders a bottle of champagne. Within the hour, her lover discovers her submerged in a bath of scalding water, dead.

At first glance it looks like an accident. No one went in with her. No one came out. But all the signs point to murder.

For DS Maeve Kerrigan, the case is a welcome distraction. But when shock news hits close to home, affecting her partner, DI Josh Derwent, she faces the toughest challenge of her career. And if she fails her world will never be the same again…
