Allan is Marjorie’s husband and a prospective local political candidate in South London. He feigns ignorance of Brenda Last’s affair when she mentions it to him. After Brenda leaves Tony Last, Allan exercises his diplomatic instincts and tries to act as peacemaker by going to each of them separately, lying to Tony that Brenda wants to reconcile, and likewise lying to Brenda that Tony will grant a divorce to avoid scandal. His ultimate plan with this is unclear beyond the desire to play diplomat, and Brenda justifiably writes him off as an “interfering ass.”
