Oliver Gurth Perkins is seventy-five, and the darkest cloud on his horizon is that the local bookshop no longer stocks paperbacks of the Times cryptic crosswords. He has an easy companionship with his wife; his dental practice is undemanding; his son is a decent enough sort; and his granddaughter who comes for the school holidays is his delight. But when a minor heart episode convinces Oliver that it’s time for him to take more interest in the lives of those close to him, further shocks are in store- Change of Heart is a glittering jewel of a book, an audacious mixture of comic invention and human insight that is Barbara Anderson at her very best.
