A rip-roaring and hilarious memoir from Stanley Johnson – father of London mayor Boris Johnson.

Stanley's story begins with a loud bang – when his father, an RAF pilot in the Second World War, crash-lands a Wellington bomber in a Devon airfield. A few years later, Stanley's parents buy a sheep farm on nearby Exmoor, where Stanley does much of his growing up. Stanley would keep his links with this much-loved rural idyll throughout his life – while going on to become an explorer, author, occasional politician and also one of the world's first environmentalists.

On leaving school in 1958, Stanley travelled alone through South America – hitching rides across the jungle on Brazilian Air Force planes – and shortly afterwards rode a motorcycle 4,000 miles from London to Afghanistan, tracing the route of Marco Polo with two friends. Stanley went on to do various adventurous jobs, before working for the billionaire John D Rockefeller III, the World Bank, the United Nations and the European Union.

Stanley married and started a family young – Boris was born in New York when his father was twenty-three – and while Boris would go on to become big news, the family's forbears also provide quite a story, as Stanley finds out. For the Johnson family's roots are not just in the West Country, but in Turkey, too – where, as Stanley discovers, his politician grandfather Ali Kemal was torn to pieces by an angry mob. Stanley visits a Turkish village where the locals are blonde – later he learns that he and Boris are direct descendants of George II.

A sparkling raconteur and experienced thriller writer, in 'Stanley, I Presume?', Stanley Johnson tells great stories in an unsurpassable style.
