Collateral has all the virtues we've come to expect from British TV

The four-part BBC/Netflix series Collateral has many of the virtues we've come to expect from British TV: fine acting, intelligent writing, great production values. Carey Mulligan plays the lead, as a detective assigned to investigate the shooting death of a pizza-delivery man, and as with most godd crime stories touching strand dislodges the entire web of events. The pizza guy is Middle Eastern, wo there's suspicion of a hate crime, and through a series of odd coincidences a Labor party leader is linked to the events of the crime (his ex-wife was the one who ordered the pizza; is she involved?) as is an Anglican vicar (her same-sex partner, in the country on false papers, signed - coincidentally? - by the same MP, is the only witness to the shooting). Clues and the witness account suggest that the shooter was a woman with military background, which sets the story off in another direction (though we fairly quickly learn the ID of the shooter, the motive remains mysterious till near the end). In fact there's so much going on in this story - written by the prominent British playwright David Hare (amazing how BBC can attract top talent) - that you should probably binge-watch this series (which I never do), as it was extremely hard to recall the plot details from night to night. Mulligan is great in her role, as are most of the secondary characters, there's some beautiful footage, especially of London at night, and the series will hold your attention throughout and reward you with some unexpected twists in the final episode.
