DI Ken Jackson's personal and professional worlds collide when a dark secret from his past comes to light. His colleague, DI Archie Bond, turns up at a police benefit boxing match with a young woman called Crystal and Ken is clearly stunned by her presence. He obviously knows the escort girl - but how? Sgt Keith Lardner is concerned when Ken seemingly becomes obsessed with Crystal and asks Dangerfield to have a word with him . However, Ken is giving nothing away and Dangerfield is left thinking that the girl could be connected with the detective's shady past in the Vice Squad. Then matters come to a head when a case of TB is uncovered at the surgery, but sufferer Gerald Norland seems reluctant to prepare a list of people he may have infected by close contact. Joanna Stevens then goes to treat Crystal's baby Emma and realises that the escort has TB also . As the TB is fairly isolated, she puts two and two together and realises that her patient was the one who infected Gerald Norland.
