Series 20 - 5. Puppet on a String

About this programme

5/6. A medical researcher accuses a rival doctor of attacking him with a syringe full of lethal drugs, but when he is later found murdered, the bitter feud between the two medics turns out to be just the tip of the iceberg for DCI Burke and the team. Both men have many enemies, especially after their drug trials resulted in a woman's death, and affairs of the heart muddy the water for the detectives in their search for the real killer. Drama, starring Blythe Duff and Alex Norton.
