Arthur and George grow up worlds and miles apart in late nineteenth-century Britain: Arthur in shabby-genteel Edinburgh, George in the vicarage of a small Staffordshire village. Arthur becomes a doctor, and then a writer; George a solicitor in Birmingham. Arthur is to become one of the most famous men of his age, George remains in hardworking obscurity. But as the new century begins, they are brought together by a sequence of events which made sensational headlines at the time as The Great Wyrley Outrages.

With a mixture of detailed research and vivid imagination, Julian Barnes brings to life not just this long-forgotten case, but the inner workings of these two very different men. This is a novel in which the events of a hundred years ago constantly set off contemporary echoes, a novel about low crime and high spirituality, guilt and innocence, identity, nationality and race. Most of all it is a profound and moving meditation on the fateful difference between what we believe, what we know and what we can prove.
