“A brother is as easily forgotten as an umbrella.” —James Joyce, Ulysses It is 1971, and Zachary Busner is a maverick psychiatrist who has just begun working at a mental hospital in suburban north London. As he tours the hospital’s wards, Busner notes that some of the patients are exhibiting a very peculiar type of physical tic: rapid, precise movements that they repeat over and over. These patients do not react to outside stimuli and are trapped inside an internal world. The patient that most draws Busner’s interest is a certain Audrey Dearth, an elderly woman born in the slums of West London in 1890, who is completely withdrawn and catatonically tics with her hands, turning handles and spinning wheels in the air. Busner’s investigations into the condition of Audrey and the other patients alternate with sections told from Audrey’s point of view, a stream of memories of a bustling bygone Edwardian London where horse-drawn carts roamed the streets. In internal monologue, Audrey recounts her childhood, her work as a clerk in an umbrella shop, her time as a factory munitionette during World War I, and the very different fates of her two brothers. Busner’s attempts to break through to Audrey and the other patients lead to unexpected results, and, in Audrey’s case, discoveries about her family’s role in her illness that are shocking and tragic.

May 4th, 1970. A week earlier President Nixon has ordered American ground forces into Cambodia to pursue the Vietcong. By the end of the day four students will be shot dead by the National Guards in the grounds of Kent State University. On the other side of the Atlantic, it's a brilliant sunny morning after an April of heavy rain, and at the "Concept House" therapeutic community he has set up in the London suburb of Willesden, maverick psychiatrist Dr Zack Busner has been tricked into joining a decidedly ill advised LSD trip with several of its disturbed residents. Five years later, sitting in a nearby cinema watching Steven Spielberg's Jaws, Busner realizes the true nature of the events that transpired on that dread-soaked day, when a survivor of the worst disaster in the US Navy's history - the sinking of the USS Indianapolis - came face-to-face with the British Royal Air Force observer on the Enola Gay's mission to bomb Hiroshima. Set a year before the action of his Booker-shortlisted Umbrella, Will Self's new novel Shark continues its exploration of the complex relationship between human psychopathology and human technological progress.

Meet Jonathan De'Ath, aka 'the Butcher'. The curious thing about the Butcher is that everyone who knows him - his washed-up old university lecturer father, his jumbling-bumbling mother, his hippy-dippy brothers, his so-called friends, his spooky colleagues and his multitudinous lovers - they all apply this epithet to him quite independently, each in ignorance of the others. He knows everyone calls him 'the Butcher' behind his back, but he also knows that they don't know the only real secret he maintains, encrypted in the databanks of his steely mind: Colonel Gawain Thomas, husband, father, highly-trained tank commander - is Jonathan De'Ath's longtime lover.
