Suspects - Season 1 Episode 4

Wealthy Terence Holland, terminally ill founder of Euthanasia Action UK, is keen to die and end his suffering. His doctor Melanie Standish calls the police when she finds him unconscious after she heard him argue with somebody. She presumed it was his estranged wife Henrietta, whom the police find asleep in the flat and who claims that she and Terence were actually discussion reconciliation. She denies giving Terence the sleeping pills and morphine found in his blood stream. The examination of a mug found in the kitchen shows that all finger prints have been wiped clean, suggesting attempted murder. Whilst Henrietta would seem to be the prime suspect Jack discovers that Terence's brother Matt and his wife would also stand to gain financially if Terence were out of the way.
