From the author of 'Stuart: A Life Backwards'; a warm and witty portrait of a harmless, eccentric, bona fide genius. Alexander Master's landlord, Simon, lives in the basement of their Cambridge house. Between teetering towers of outdated maps and slagheaps of plastic bags, Simon eats endless meals of tinned kippers and plans trips on the Cambridge public transport system. But Simon was one of the greatest mathematical prodigies of the twentieth century. He spends his time between train journeys working on a theoretical puzzle so complex and critical to our understanding of the universe that it is known as the Monster. Poignant and comical, 'Simon: The Genius in my Basement' is about the frailty of brilliance and how genius matters very little in the search for happiness.

Unique, transgressive and as funny as its subject, A Life Discarded has all the suspense of a murder mystery. Written with his characteristic warmth, respect and humour, Masters asks you to join him in celebrating an unknown and important life left on the scrap heap. A Life Discarded is a biographical detective story. In 2001, 148 tattered and mould-covered notebooks were discovered lying among broken bricks in a skip on a building site in Cambridge. Tens of thousands of pages were filled to the edges with urgent handwriting. They were a small part of an intimate, anonymous diary, starting in 1952 and ending half a century later, a few weeks before the books were thrown out. Over five years, the award-winning biographer Alexander Masters uncovers the identity and real history of their author, with an astounding final revelation. A Life Discarded is a true, shocking, poignant, often hilarious story of an ordinary life. The author of the diaries, known only as 'I', is the tragicomic patron saint of everyone who feels their life should have been more successful. Part thrilling detective story, part love story, part social history, A Life Discarded is also an account of two writers' obsessions: of 'I's need to record every second of life and of Masters' pursuit of this mysterious yet universal diarist.

'Stuart does not like the manuscript. He's after a bestseller, "like what Tom Clancy writes". "But you are not an assassin trying to frazzle the president with anthrax bombs," I point out. You are an ex-homeless, ex-junkie psychopath, I do not add.' This is the story of a remarkable friendship between a reclusive writer ('a middle-class scum ponce, if you want to be honest about it, Alexander'), and Stuart Shorter, a homeless, knife-wielding thief. Told backwards - Stuart's idea - it starts with a deeply troubled thirty-two-year-old and ends with a 'happy-go-lucky little boy' of twelve. This brilliant biography, winner of the Guardian First Book Award, presents a humbling portrait of homeless life, and is as extraordinary and unexpected as the man it describes.
