So sorry to hear about your loss, Betty 
to you too, plornish
Thanks for the welcome, Remus (I'm not new on the thread, but thought I'd get that previous post out of the way while I was feeling soppy)
I went to the Elly Griffiths event last night, bibliomania, and it was really enjoyable! The venue was packed - hundreds of people (of which my friends and I seemed to be the only ones under 60...). Elly Griffiths herself was great: warm, funny and generally lovely.
She started by reading a bit from her new book, The Lantern Men, which was suitably armospheric. Apparently, there is a bit of a cliffhanger ending, but EG says that she has already got ideas for books 13 (tentatively titled "The Night Hawk", about metal detectorists) and 14. She's also got a new stand-alone book (like The Stranger Diaries) coming out in October. Apparently, we are to think of Jeremy Bamber (re her character Ivor March) and the Bloomsbury Group when reading The Lantern Men
.
There was a lot of talk about the landscape (which is fairly local to us), including an interesting discussion about why there are suddenly so many crime novels set in East Anglia - as one person put it, "is Oxford full up now?". General agreement that East Anglia is not only full of bodies, but some of those bodies have been here a very long time, making it good for archaeological mysteries. Round here is also full of stories and legends (our local paper is always full of sightings of the Fen Tiger), and the landscape is both ancient and spooky as well.
I was tickled by a couple of pieces of trivia. One is that the house in the current book, Greywalls, is named in homage to Malcolm Saville's Lone Pine books, which pleased me hugely because I loved these as a child. Another is that Francis Pryor, whose excavation of Seahenge influenced The Crossing Places, has written his own archaeological crime novels, and has put Ruth Galloway into one of them. I'm unclear about the details (whether this is the most recent book from 2017, or an impending one - and whether he has literally mentioned RG, or has just based another character on her), but am motivated to find out more.
