Season 10

Lisa meets Zoe, who is as much like her as an identical twin, but entirely out of the common rut - and dramatic events ensue which change both their lives.

Nicholas Hawthorne is a young engineer, recently made redundant and looking for a job in the boat-building industry. He has a very realistic nightmare about a woman being murdered. Then, on an unsuccessful dinner date, Nicholas spots Julian Sorensen, the boss of the firm which has laid him off, and the woman with him isn't his wife. Sorensen pays Nicholas's dinner bill. The next day, trying to pay back the money, Nicholas sees a photograph of Sorensen's wife - and she is the woman who was killed in his dream... Nicholas decides to investigate.

Part two of two. Nick's attempted suicide implicates him in Emma's death and Annabel casts light on the mystery.

A boy obsessively collects poisons - and then he tries them out, with deadly results.

May Thrace and June Symonds are sisters, but their lives are very different. While June lives in the lap of luxury, May is struggling. And May becomes convinced that she has been done a great injustice.

After accepting her sister's offer of reconciliation, May emerges from her mousy shell and seduces her sister's lover.

Hugh and Cecily Branksome retire to the seaside town where they grew up. There they meet again Arnold Cottle, an old boyfriend of Cecily's. She goes to look for a public seat given to the town by her late father, who was a local alderman, and finds it was destroyed and later replaced by another seat given by a suspected murderer. With Arnold's help, she sets out to investigate the unsolved murder.
