Random House Paperbacks The silhouette edition paperbacks
        represented Random House's first general release of all
        the available titles in paperback format. The name "Alfred
        Hitchcock and the Three Investigators" was put into
        a oval shape surrounding a silhouette of Alfred Hitchcock
        in the upper right corner of the cover, making it less
        prominent. Cover art for these books was provided by
        Robert Adragna.
