The Green Knight — Iris Murdoch

Full of suspense, humor, and symbolism, this magnificently crafted and magical novel replays biblical and medieval themes in contemporary London. An attempt by the sharp, feral, and uncommonly intelligent Lucas Graffe to murder his sensual and charismatic half-brother Clement is interrupted by a stranger -- whom Lucas strikes and leaves for dead. When the stranger mysteriously reappears, with specific demands for reparation, the Graffes' circle of idiosyncratic family and friends is disrupted -- for the demands are bizarre, intrusive, and ultimately fatal.
