A murdered ex-soldier. A British Army conspiracy. Can DC Ruth Hunter and DC Lucy Henry uncover the killer's identity before there's yet another cover-up.

When ex-soldier Ashley Campbell is brutally murdered outside a Peckham nightclub, Ruth's first thought is that it is gang related. Yet, as the investigation progresses, it seems that the victim's time as a recruit at Cranleigh Barracks might hold the key to the true identity of the murderer. As Ruth and Lucy uncover a brutal culture of bullying, racism and sexual abuse at the barracks, it seems that several officers in the British Army will go to any lengths to protect their identity.

Can Ruth find enough evidence to bring the officers to justice? And what will she do when new evidence appears to suggest that CID should have been looking far closer to home for Ashley's killer?
