First, the broadcast: On May 21, 2012, BBC Radio 4’s Miles Jupp presented a 30-minute programme on locked rooms, the third in a series of fairly light-hearted treatments of mystery themes. Interviewees were: Mike Ashley, Paul Doherty, Bob Adey, Christopher Fowler, Jasper Fforde, Paul Halter, John Pugmire, Soji Shimada, Denise Mina and a representative of a mainstream publishing house who, true to form, said nobody was interested in reading that kind of stuff (the promotional web post for the broadcast attracted 492,000 listeners). Here is a Transcript of Broadcast.  The MP3 of the broadcast is too long for this website, but if anyone interested in listening to it sends me an e-mail at pugmire1@yahoo.com I will make the file available through Dropbox.  There is also some preparatory material available, most of which was not used, but will hopefully be of interest:

Publishers Weekly Talks With John Pugmire – 1st September 2017
It was very gratifying for me, a mere one-man-band Print On Demand publisher, to get my own interview with the prestigious Publishers Weekly.  The occasion was a literary event: the first US publication of possibly the rarest book in detective fiction: Stacey Bishop’s Death in the Dark, first published in London in 1930 by Faber & Faber, where T. S. Eliot was senior editor.  The LRI edition contains an Introduction by Martin Edwards, a very successful author in his own right and President of The Detection Club, and a fascinating Afterword by Mauro Piccinini, an expert on George Antheil (Bishop’s real name). It turns out that the story behind the book is almost as incredible as the fictional work (although, in the interests of space, my references to Martin and Mauro — and LRI’s honkaku masterpieces — didn’t make the final cut).
