Night judgement at Sinos

The island of Sinos has become a prison for political offenders from the Greek mainland. A fortress of grim solitude and secrets, Sinos is the last place anyone would voluntarily enter but deep sea diver Jack Savage has little choice. After losing his boat, Savage is approached by shipping magnate Dimitri Aleko. The multi-millionaire has taken an extreme interest in Savage's background as a Royal Marine Commando and his expertise in underwater sabotage.
