On Christmas Day, Detective Chief Inspector Harry Brock’s celebrations are interrupted when he is called to a murder in a car park at Heathrow Airport.  The victim is businesswoman Kerry Hammond who has been stabbed to death in her top-of-the-range Jaguar. 

 

During the course of a complex investigation Brock and his assistant, Detective Sergeant Dave Poole, discover that there is much more to Kerry Hammond than at first was apparent.  Not only does she have a string of lovers, but her estate agent husband is not what he at first appears to be.

 

It is not long before Brock and his team uncover a gunrunning operation that stretches from the South of France to Central London.  The arrests that follow lead them to a shadowy figure in Bethnal Green who is believed to be the mastermind.

 

Faced with a plethora of suspects, each is eventually eliminated until Kerry Hammond’s killer is finally arrested.
