We reach the halfway point of Amis's fiction, a long meditation on the realities of the writer's life and the futility of revenge.  Some poetic allusions to Philip Larkin's The Trees and Wendy Cope's Tumps (typically useless male poets), and the mystery of what a planesaw is, enliven Amis writing at the top of his game on the sad and depressing life of Richard Tull, a novelist whose early promise has evaporated into hackwork.
