Vera S04E01 - On Harbour Street

Joe's daughter is a witness to the death of a pensioner, seemingly stabbed, on a rush hour train she and her father were travelling on. Her seemingly quiet life turns out to be anything but as Vera's investigation begins to unravel a tangled web of lies and deceit. An old friend of Vera's father appears to hold the key to the entire mystery, which involves unraveling a murder committed thirty years previously, a rape which resulted in a child whose identity has been shrouded in mystery, and an affair which nobody suspected would ever be likely to have taken place. Vera realises that the answer may lie in events which have started to repeat themselves.
