At present I'm working on revisions to the new Lake District Mystery, The Crooked Shore. I'm still reluctant to travel to the Lakes to do a final bit of scene-checking, but the book is now getting into reasonably good shape ahead of being sent to the editor. This one is rather different from earlier books in the series, with more emphasis on psychological suspense.
I've also been working on a couple of non-fiction projects, one of them speculative at present. More about these at a later date.
In the meantime, I've been doing what I can in terms of promotion, most recently on Monday, a Facebook Live chat with Mitzi Szereto about my essay on Dr Harold Shipman, the serial killer, "The First of Criminals": https://www.facebook.com/watch/live/?v=269733067694694
And last but by no means least, I've been thrilled by a review of Mortmain Hall by A.N. Wilson, of all people. The Booker Prize-nominated author describes the book as: "an ingenious modern 'take' on the classic whodunnit...It's a winning formula...A whole page would not give me space to explain the intricacy of this story. A tangle of satisfying clues and a pleasing denouement in the classic Christie manner". Very pleased with that!
