The Cave — Bruce Crowther

Locked away for many years in maximum security, the Caveman never speaks. Savagely beaten before facing trial for the slaughter of little children, the evidence against him is never tested in court. Did he commit these unspeakable acts? Or is the real killer still free? Is the truth hidden in the Caveman's damaged brain? Answering a call for help when an old friend is suspected of molesting a missing teenager, Jack Haley becomes entangled in present and past crimes. The people around him - an old girlfriend, her politician father, beautiful twin sisters, small-time crooks, policemen - all have secrets that won't stay buried.
