Murder in a chess tournament? Nesta was as surprised as anyone.
After joining a local chess club in the town of Llangollen, she learns that there is far more to her favourite board game than pawns and bishops. When a real-life checkmate sends the national championships into complete chaos, Nesta and Darren must put their heads together and solve this new mystery before the game is up.
Danger on a Llangollen River is the ninth instalment of the Nesta Griffiths Mysteries, where murder is just a little too close to home.
