Among these entries in Part 26 of the online Addenda to the Revised Crime Fiction IV, by Allen J. Hubin, are two I’d especially like point out to you.

   First of all, the entry for Michael E. Knerr has been completely revised. New data had been spread out over several parts of the Addenda; it’s now combined in one spot in Part 26, with one newly discovered book also included. That book also makes Mike Travis a series character, and this fact is now noted.

   Secondly, I have been in touch with the family of Jon Messmann, and I talked to his son Alan for about 45 minutes late last week. As a consequence, the autobiographical portion of his entry has been rewritten, and a newly revealed pen name is made known for the first time.

JOSEPH, ALAN. Add: Pseudonym of Jon (Joseph) Messman, 1920-2004. Under this pen name, the author of two books included in the Revised Crime Fiction IV. Series character: Logan, in both:
       Killers at Sea. Belmont, pb, 1970. Setting: South Carolina. “Logan finds a dead man on the beach [leading] to danger, diamonds and death.”
       Logan. Belmont, pb, 1970. Setting: Ship. [Mystery and adventure aboard the Sea Urchin.]

KNERR, MICHAEL E. 1936-1999. (Corrected dates.) For a lengthy discussion of the author’s mystery fiction, see a review of his private eye novel Travis posted earlier here on the Mystery*File blog. A biographical reminiscence of his life by John F. Carr can be found in this follow-up post. Below is a completely revised entry for the author; add the books indicated with a (*).
       * Heavy Weather. Tower, pb, 1979. Setting: Ship. “On the Mexico run the Pandora carried a cargo of drugs, danger and death!”

       Operation: Lust, as by M. E. Knerr. Epic, pb, 1962.
      * Port of Passion, as by M. E. Knerr. Imperial, pb, 1965. Series character: Mike Travis. Setting: Mexico. [Travis tries to discover who killed a Mexican deep-sea diver.]

MESSMANN, JON (JOSEPH). 1920-2004. Pseudonyms: Alan Joseph, q.v., Claude Nicole & Claudette Nicole (add the former). House pseudonyms: Nick Carter & Paul Richards. In the 1940s and early 50s, the author of many comic book stories for Fawcett Publications. (See this webpage for more information, noting however that in this short biography of him, his name is incorrectly given as Eric Jon Messmann.) Under his own name, the author of 18 crime and suspense novels cited in the Revised Crime Fiction IV, including seven about men’s adventure series hero Jefferson Boone, The Handyman, and six with Ben Martin, aka The Revenger. As a writer of adult westerns, Jon Messman was better known as Jon Sharpe, author of many of the early adventures of The Trailsman books, including the first one, as well as most of the Canyon O’Grady books.

MILLER, BEN E. Author of two detective novels included in the Revised Crime Fiction IV. Series character in each: Cory Barnett, nominally a detective for the Chicago police force.
       Death Deal. Powell, pb, 1969. Setting: Paris, New York City. (Add the former.) [Barnett, acting as a US agent, is assigned to protect a political target in France.]
