On a sullen, cloudy July day ten years since 7/7, the happy, confident and optimistic British Prime Minister is visiting a charity in East London. It's just two months after the general election which saw John Campbell's government returned to power with a clear majority, the economy is on the mend and the coalition is fast becoming a bad memory. Suddenly, a man appears out of the crowd and shoots him three times in the chest. Step forward Alex Cartwright (Andrew Scott), MI5 Chief Counter Terrorism Officer who must find out the truth. But it's easier said than done, as he discovers that whoever ordered the assassination has covered their tracks very well indeed. Along with Ellen Townsend, his trusted second-in-command, Cartwright finds himself embroiled in a race against time which leads him into the murky heart of Westminster...and beyond. From the pen of renowned screenwriter and novelist M J Arlidge, featuring an established British cast and with an exclusively-composed musical score, Six Degrees of Assassination is truly a thriller not to be missed.
