There is a recurring image in Once Upon a Time in Londongrad (Sky Documentaries/Now): a shot taken in 2014 in central London, outside an old block of serenely expensive flats nestling between the Swedish and Swiss embassies. A section of the beautiful iron railings separating the property from the pavement is missing, replaced by a garish mass of carelessly applied police incident tape.
The railings have been removed because the British property speculator Scot Young has recently fallen from his fourth-floor window and impaled himself. This death is then investigated by Heidi Blake and her team of journalists at BuzzFeed, a trail that leads to a Pulitzer nomination, Blake’s book From Russia With Blood and now this punchy six-parter.
