Water washes away everything, even the bodies. Lake Zurich is Rosa Zambrano's beat. Once a detective with the Criminal Investigation Department, she's now exchanged serious crimes for the serenity of the water, patrolling it daily as the first female officer in Zurich's maritime police force. Then one day, the body of Dr Jansen, a renowned fertility doctor and successful biotech entrepreneur, is dredged up in a fisherman's nets. The case hits close to home for Rosa -she was a patient of Jansen's and saw him only days before he was killed. The investigation leads her from the opulent villas on the lake's shores to genetic research labs and a thriving escort service on the outskirts of the city -and to four women, each of whom has rejected the hand she's been dealt.
