The brutal murder of an art dealer leads Susan and Luke down some mystical paths.

A drive-by shooting apparently kills a businessman, but the plot thickens when it's found he was murdered in three different ways.

Luke's involvement in a case is so intense it jeopardizes his objectivity, while Susan and Adrian must deal with a prisoner to find the murderer.

The discovery of legs at a rubbish dump sends the team in different directions as more and more leads turn up.

Luke is fascinated by a skull found at a construction site, but the mystery behind the skull may be more fascinating than its identity.

Susan works the case of a missing teenager who is presumed dead, whilst Luke has to get into the head of a killer who seems to have pulled off the perfect crime.
