Now working summer months only and encouraged by wife Audrey to seek other interests, Jack's first excursion into the mysteries of fishing produces as even bigger one of its own. But what starts as a casual attempt at solution, soon leads the ranger into waters far murkier than he has ever delved before. Could an old Broadland mystery somehow be connected to something infinitely more sinister?

Discovering the answer unearths an even deeper conundrum that causes Jack to reconsider whether justice really is always best served by the truth.
