Book and wrapper still good even though it belonged to a library before >>> When Nan Mansfield arrives home to hear her husband, Roy, on the telephone arranging a clandestine meeting in Regent's Park, she is determined to find out what he is involved in. Is there another woman -- or can it be blackmail, drugs, even treason? Roy is a Member of Parliament who was helped into politics by Cyprian Slepe, a brilliant eccentric who lives with his sister, Celina, in a decaying Stately Home. Nan comes to believe that Cyprian is connected with Roy's mysterious activities. Helped by an engigmatic taxi-driver, she delves deeper and deeper, while her love and loyalty war with her ever-increasing suspicions, until at last she discovers that her whole life is in jeopardy.
