The death of Valerie Dupree at a plastic surgery clinic leaves Richard and the team baffled, as it would appear that Valerie killed herself. Dr Jones reveals that Valerie was suicidal, but Richard is convinced that Valerie was actually murdered - her... (more) cup of tea suspected to be poisoned. However, as the results come back negative, Richard finds it difficult to find the means. Suspect Jayne believes that Valerie was having an affair with Paul, but Dr Jones reveals she was having an affair with Paul, providing them both with alibis. Richard then learns that the clinic itself was an illegal operation, providing criminals with new identities.
