A young man's drinking binge sets in motion a sequence of violent and lethal crimes, leading to a suicide verdict that DI Harry Lambert suspects is more likely to be foul play. Continuing his own investigations, the Swansea detective is soon warned off the case by SOCA... but leaving things be is impossible when his team begin to find links between the suicide and a different murder case they are looking into. Events take a bizarre turn when three petty criminals become involved in a deadly game of vengeance, and Lambert's prime suspect disappears, along with a respectable young man who surely can't be away on business as is claimed. When Lambert eventually discovers the whereabouts of the missing persons, he knows the game will become even more violent, but should he trust his own instincts that there is an even greater treachery afoot?
