Deep Dark Blue

Water washes away everything, even the bodies.

Lake Zurich is Rosa Zambrano's beat. Once a detective with the CID, she's traded in serious crimes for the serenity of the water, patrolling it daily as the first female officer in Zurich's maritime police force. But when the body of Dr Jansen, a renowned fertility doctor and successful biotech entrepreneur, is dredged up in a fisherman's nets, Rosa must call on her old training to solve his murder.

This case hits close to home for Rosa - she's a patient of Jansen's, and had her eggs frozen at his clinic only days before he was killed. Her investigation leads her from opulent villas on Lake Zurich's shores to genetic research labs and a thriving escort service on the outskirts of the city - and to four women, each of whom in their own way have rejected the hand they have been dealt by biology or fate.
