Alexander Hay Japp and Japp's conversation attracted Stevenson and his father. Stevenson read to Japp the early chapters of "Treasure Island", then called "The Sea Cook", and Japp negotiated its publication in "Young Folks". Subsequently Stevenson and Japp corresponded on intimate terms; and Japp's last work, "Robert Louis Stevenson: a Record, an Estimate, and a Memorial" (1905), was the result of their contacts. Japp was versatile and prolific writer, writing under pseudonyms such as "H. A. Page", "A. F. Scot", "E. Conder Gray", and "A. N. Mount Rose" as well as in his own name. In his own name he issued in 1865
Jack the Ripper in fiction alter-ego "Jack Hyde", but was still condemned by critics "as a tasteless exercise". The Dolph Lundgren vehicle "Jill the Ripper" (2000) reverses the traditional genders of victims and villains, with a female Ripper and male victims. In "Time After Time" (1979), based on the novel of the same title, Jack escapes in a time machine to modern-day San Francisco and is pursued by H. G. Wells. The pursuer was originally slated to be Robert Louis Stevenson in a link to the author of "Strange Case of Dr Jekyll and Mr Hyde", but he was written out in favour of Wells.
