One Leg Too Few by William Cook is the first full-length dual biography of Peter Cook and Dudley Moore, and the first to be written with the consent and cooperation of both of their estates, by bestselling author of Tragically I was an Only Twin.

"With wit and warmth, William Cook charts the rise of a remarkable 20 year comedic partnership - and how it fell apart." The Observer "A well written biography by a talented writer... William Cook charts the progress of their unlikely marriage very perceptively" Daily Mail "This is the definitive biography of the double act; not only informative but also vastly entertaining." Sunday Express "Sympathetic yet sharp-eyed, he gives a vivid, poignant sense of the forces that held them together and which, ultimately, tore them apart." Mail on Sunday "Funny, sad and always entertaining" The Independent

William Cook is the acclaimed author of Ha Bloody Ha - Comedians Talking (Fourth Estate), The Comedy Store - the Club That Changed British Comedy (Little, Brown), two bestselling collections of Peter Cook's writing, and most recently the extravagantly well-reviewed Kiss Me Chudleigh: The World According to Auberon Waugh. He has worked for the BBC and written for the Guardian, the Mail on Sunday and the New Statesman.
