His name was Zac. His last name depended on who knew him: an oligarch’s son, or the middle-class child of professionals. When his body was found in the Thames, it might have been dismissed as a teenage suicide-if not for a surveillance camera on the outside of Britain’s secretive spy agency across the river.

London Falling confirms Patrick Radden Keefe as one of the premier investigative journalists of our time, a writer of narrative non-fiction with few equals. In Say Nothing, he grippingly examined Northern Ireland’s ‘Troubles’ through the abduction and murder of a young widow. His reporting here is jaw-dropping. He then weaves the facts-the hours of interviews, including with Zac’s parents, and hundreds of pages of court documents-into a narrative as gripping as any true-crime thriller, with a cast of rogues (Rogues, another Radden Keefe masterpiece) and more twists than a drunken string of spaghetti. Just when you think you know what happened, he delivers more.

But London Falling is much more than a ‘who dunnit’.

Radden Keefe’s Empire of Pain, about the Sackler family who made millions while fuelling the opioid epidemic in the United States, was shortlisted for the Financial Times and Business Book of the Year. London Falling is also a book about business-the seedy side of it in 21st-century London, which he describes as “a twenty-four-hour laundromat for dirty money… full of crooks with pretensions to legitimacy and businessmen who seem a little crooked.”

London Falling has been atop the New York Times bestseller list since publication. Deservedly.
