Ian Covell, from a post he made to the FictionMags Yahoo group:

   Thanks for alerting me that so much had been cleared up (though I can tell you the bibliography still has a couple of errors).

   I am “pleased” to find that the many books I thought were missing (there was a note [F&SF July 1974] that Runyon had written “over 30 published novels in 14 years of writing”) turn out to be much less (just over 20), and indeed, I have half of them.. definitely the SF, though not the Ellery Queen’s or the adult stuff.. The Black Moth is one of the finest, darkest thrillers I have ever read… and Color Him Dead is an unpredictable, excellent work. Soulmate is definitely adult horror. .

   The corrections and additions pointed out by Ian in the remainder of his post have already been incorporated into the bibliography. They include:

INCARNATE, the paperback from Manor, was published in 1977. (Previously “no date.”)

KISS THE GIRLS AND MAKE THEM DIE. Correct spelling of Runyan to Runyon.

I, WEAPON. The hardcover was published in July 1974, not 1971, which necessitated a change in the chronological order in the SF section. The paperback from Popular Library appeared in December 1977.

   Short Stories:

“In Case of Danger” F&SF, December 1975 — the actual title is longer and funnier, “In Case of Danger, Prsp the Ntxivbw”

      and add the following:

“Happiness Squad” – Fantastic, March 1967
“The Youth Addicts” – Worlds of IF, May 1967

   Charles also had a letter appear in F&SF, September 1975. [This does not appear in the bibliography, but it is certainly worth a mention here.]

   Ian also cited one British paperback reprint of one of Charles’ books, but since this means that other UK editions are omitted, I’ve decided not to include it for now, based on an “all or none” philosophy.

   Also from Ian: “I have a penned note of something called Hang Up from Gold Medal, circa 1969, but it really is just penciled in, not confirmed; may be an early title of No Place to Hide or even Power Kill.”

   And from Allen J. Hubin: “I’ve got the three Mark West titles listed in Addenda #14, each with a dash.” The dash, of course, indicating marginal crime content; the Addenda referring to the Revised Crime Fiction IV.

          —

   Thanks to Ian Covell in a followup email, and a judicious search of the Internet, I now have equal-sized cover scans for all of Charles Runyon’s novels. (One is a third printing, but other than that, it’s complete.)

   I’ve also cleaned up a couple of glitches that I created this morning. See the bibliography as it appears now on the primary Mystery*File website.

[UPDATE] 05-04-07. An email from Charles Runyon:

  Dear Ian, et al:

   Thanks for the kind words and the help in researching my past. You dug up some interesting material, not the least of which was that enigmatic Hang-Up which was supposedly published by Gold Medal in 1969. According to my wife’s Little Black Book, that was my original title for No Place to Hide.

   I sold a story entitled “The Day it All Hung Out” to Escapade Magazine in October 69. An amusing little tour de force, which I remember reading when it came out. I haven’t yet been able to find any copies of it in my files, but I’m keeping my eyes open.

   I sold a few other stories to the men’s magazines, such as Adam Yearbook, “There Must be More than This” and Knight, “The Appointment” but “The Day…” was the best according to my memory — not excluding “The Naked Bums,” which was the title Men put on their serialization of The Death Cycle. (If you’re looking for the Ultimate in Egregious Reprints, that’s gotta be IT.)

   I think the discrepancy in the number of books published arose from the fact that I counted foreign language editions at the beginning. Or maybe I was just exaggerating.

   Regards to you, Ian, and everybody else, Chas.
