Stay silent – or die.

Sergeant Kieran O'Regan was responsible for hunting down killers. Now his decapitated body has been found in a graveyard, a tin whistle stuffed into his throat.

O'Regan was due to give evidence at a trial for police corruption. His gruesome murder sends a clear message: only silence is safe.

DCI Katie Maguire is determined to uncover the truth. But corruption in the Garda stretches back decades. As more officers are horrifically silenced, Katie must be careful who she can trust – or risk meeting the same fate…

Perfect for fans of Peter James, CJ Tudor and Chris Carter, Dead Men Whistling is part of the darkly original million-copy-bestselling DS Katie Maguire thriller series, which can be read in any order.
