Howard entered the cab. As the two continued arguing, the cab driver raced to the 23rd Precinct at Third and 104th. Suddenly, the driver heard three gunshots fired inside the cab. Rushmore had shot his wife in the right side of the head and neck then put the pistol to his temple and shot himself. Harrison heard about the murder-suicide when a taxicab picked him up at Idlewild Airport. The driver told Harrison that the publisher of Confidential just killed himself and his wife, momentarily confusing the unmarried Harrison. Later Harrison refused to believe the suicide narrative and thought Howard Rushmore was murdered. He remained loyal to Rushmore even after the California trial and the Rushmores' scandalous deaths. The once biggest-selling magazine in the United States plunged to a circulation of 200,000, smaller than its December 1952 début. The rights to Whisper and Confidential were sold off in May 1958 for $25,000. The buyer, Hy Steirman, further toned down the content of both magazines. But Harrison remained in publishing. In 1963 he started a much smaller magazine called Inside News (in which he authored "Who Really Killed Howard Rushmore?"), as well as one-shot publications like New York Confidential. Harrison continued to live in New York City during the next two decades under an assumed name, while plotting a comeback. But lacking the financial pressures that drove Harrison to create his previous magazines, he was essentially retired, living his remaining years at "the Delmonico Hotel, at 59th Street and Park Avenue." Robert Harrison died in 1978 with his long-time mistress, Regi Ruta, at his side; that same year Confidential was shut down. Legal activity Following a highly-unflattering article about Cuban dictator Fulgencio Batista, an attempt was made to ban the magazine from sale in Cuba. In the May 1955 issue of Confidential, "Doris Duke and Her African Prince" appeared. The story alleged that Doris Duke had an affair with a "Negro handyman and chauffeur," whom the article said she once employed. In July 1955, Doris Duke sued the magazine for $3 million, claiming libel. In August 1955, US Postmaster General Arthur Summerfield barred Confidential from the mails. "Post Office officials objected to among other things, a racy description of a stripteaser's gyrations and a 'questionable' cheesecake photograph of Hollywood Starlet Terry Moore," originally appearing in the Istanbul, French-language newspaper, Millyet.
