In the pretty village of Morton Fendle, young Simon Bright is found dead, apparently of carbon monoxide poisoning, inside an old World War II Humber. When investigations show that Simon was hit over the head before the noxious gas caught up with him, Barnaby and Jones realise that they have a murder on their hands rather than the suicide which was first suspected.
The plot thickens as the police try to locate Laura Sharp, Simon's girlfriend, who seems to be on the missing list. Has she met with foul play too or is something else going on? When another body is discovered and one of Laura's friends survives a murder attempt, Barnaby must conclude that Laura is somehow connected. The question is, how?
Watch and see!
