Burned to the Bone Into the Vipers' Nest

Under the Knife is a case featured in Criminal Case, appearing as the tenth case of the game as well as the city of Grimsborough. It takes place in the Industrial Area, a district based in Grimsborough.


The police found a plastic surgeon named Alan Cardwell left for dead in an alley. The killer turned out to be Paul Oaster, a writer.

After Jones tricked Paul into confessing the murder, Paul said that he fell in love with a singer named Samantha Warner and would do anything to protect her. Paul could not bear it when it came to his attention that Alan had an affair with Samantha – though the surgeon was already married. In retaliation the writer cornered Alan in Alberta Alley, before stabbing him with a candlestick and fleeing the scene. For his actions, Paul was sentenced to life in jail.
