Circles Of Deceit (1996) 3/3 "Kalon" TV Crime Thriller (Dennis Waterman, John Hannah, Simon Cadell)
When Major Robert Turner (Nicholas Pritchard) is found shot through the head outside the army base where he was stationed, Neil's superiors task him to uncover the identity of the killer.
(The release dates of episodes in this series don't coincide with the logical order from a narrative perspective, due to 1/3 "Sleeping Dogs" being delayed for broadcast until 1996 - perhaps due to political sensitivity concerns of the time, due to the subject matter).
(Plot spoilers from here)
Neil's investigations lead him to Jason Sturden (John Hannah), assistant to crooked merchant banker Brendan Rylands (Simon Cadell), the senior partner of Cottrill's, a highly lucrative private bank situated in the heart of London's financial district. Neil discovers that Rylands is the mastermind of a drug-smuggling and money-laundering ring involving Japanese banker Osuna (Jack Klaff), wealthy Hungarian property developer Paric (Constantine Gregory), and a serving officer in the Royal Air Force, Alec Dwyer (Struan Rodger). Neil struggles to work out how their operation is connected to Turner's death, but his main priority soon switches to the safety of Turner's girlfriend, Liz Baker (Saskia Wickham), a serving officer in the British Army, whose police protection has aroused the suspicions of Rylands and his associates.
First broadcast April 8th 1996.
