It's a stunning summer evening in the Lake District. The day has been hot and long, and tourists are only just leaving Rydal Water. One solitary rowing boat remains; face-down in the reeds. Underneath is the body of a young woman.

DI Kelly Porter heads to the scene but when she arrives she gets another call. A suspected suicide at a health and fitness conference nearby. Two deaths in one day is never a good sign.

Neither case is as open and shut as Kelly had hoped. Both victims had links to the wellness industry. Both had secrets ready to be shared. And it seems they paid the ultimate price for them
