## About the story

New Year’s Day, 1997. Noah Yalland has been volunteered for a swimming relay along the Devon coast. He expects cold water, bruised dignity and a drink at the Bleeding Gull. Instead, Sinéad Kelleher, her team’s Blue Six, is missing. She is found dead inside Hollow Eye Lighthouse. Relay times, photographs and conflicting accounts draw Noah towards events from a summer long ago. The seventh Treggan Bay mystery follows a case whose questions may hurt people he cares about. Best read in series order.
