Olympic rowing hopeful & senior Metropolitan Police officer DCI Rebecca Meredith goes out alone to train on the river in Henley on a dark afternoon in late October -- & doesnt return. When a desperate search by the police & a K9 team reveals the possibility of foul play Scotland Yard wants one of their own on the case. Detective Superintendent Duncan Kincaid returning from celebrating his marriage to long-time partner Detective Inspector Gemma James is called to Henley to investigate. He soon finds that the world of elite rowing can be brutal & that Rebecca Merediths ex-husband was not the only person with good reason for wanting her dead. Then when a search-&-rescue team member is threatened Kincaid realizes the case may be even more complex & more dangerous than he believed. But it is only when he enlists Gemmas aid that they find that the answers lie closer to home than they could have imagined -- & are infinitely more deadly. It seems that more than one innocent life depends on their ability to track down the killer.
