The following may, for some, contain spoilers.
The main reason, in my view, for watching this British mini-series is the performance of the reliably-excellent Michael Kitchen, here playing against type as Steven Vey, a successful barrister and a man as arrogant as he is amoral. Though married, Vey has eyes for a young secretary in his office. She is sufficiently flattered by his flirting that the two end up one evening after work at her apartment. Sensing that she has allowed things to go too far, she tries to end their evening together, but Vey is not about to be rebuffed, and he proceeds to force himself on the young woman. Not long after this incident, Vey receives a coveted appointment to the bench. The young woman, wanting some sense of justice but believing that she would have little chance of getting it in court, contacts Vey with an offer: if he resigns his judgeship, she will remain quiet about what he did to her; if he does not, she will go public.
The stage is set for a promising drama, which makes what follows all the more disappointing. First, the story shifts from London to Birmingham and to a young petty thief, Eddy Doyle. Doyle learns from his mother that the man he thought was his father is actually his adoptive father, that his biological father is a man by the name of... Steven Vey! Learning this, Doyle is off to London to try to locate Vey. In what follows, the story goes off the rails, at least it did for me, because of the coincidences the writers invoke to intersect the paths of Doyle and Vey and of Doyle and the young lady who was Vey's victim. If you are tolerant of these preposterous twists, then you will probably be as impressed with this mini-series as others here are. The performance of Michael Kitchen makes this worth watching but not, in my opinion, worth owning.
