Two young people travelling through Italy are caught in the rain and hitch a lift with chilling consequences. Richard and Mary have been together throughout University, and the trip to Italy had been planned long ago. But before they set out, Richard had a brief affair with Alice, and his confusion and Mary's suspicions have started to change everything. Together they make a series of small choices which ultimately lead to disaster. In delicately powerful prose, Peter Robinson carefully, painfully, and tenderly depicts the relationships before and after the brief and traumatic event at the heart of the novel. September in the Rain is a book about the responsibilities of love; about accidents and decisions; about unforeseen and dreadful consequences.
