Traitors gate

Someone is passing secrets to the Germans.... Britain's strategy in Africa is finding its way to the kaiser's government.... As Police Superintendent Thomas Pitt investigates the leak in the Colonial Office, he quietly looks into the tragic death of his childhood mentor, Sir Arthur Desmond. Pitt believes he was murdered, and that the crime is connected with the treachery in the government. He makes little progress...until a second murder reverberates through London. In the small hours of a May morning, a Thames waterman finds the strangled body of an aristocratic society beauty floating near lonely Traitors Gate. Only then do hard-pressed Pitt and his clever wife, Charlotte, begin to untangle the threads of passion and intrigue, to see clearly the pattern of tragedy and frightening evil that Pitt must deal with...at the risk of his career--and his life.
