Domenica de Rosa, I do believe is better known under her nom de plume I've read all her Ruth Galloways and enjoyed those. I shall make a mental note of the rest of your list Early and look up some of your recommendations. Have read Allison Pearson.
Ah! Elly Griffiths.
For anyone who doesn't know about Who Else Writes Like? It's a database started in Oz and NZ I think, first published under the title in 1993, designed to help fiction readers who have read all the books by their favourite authors and are seeking new names to try. Of course, no author writes exactly like another, but the selection of alternatives provided here should help to narrow the choices from the hundreds of titles available. The basis for the initial selection of authors were those who were the most borrowed according to the lists compiled by the Registrar of Public Lending Right. These are supplemented with names suggested by a small team of volunteer advisors based in libraries in different parts of the United Kingdom and also in Australia. As a general rule the author should have had three novels published.
For Ellie Griffiths, they suggest:
Tasha Alexander
Harry Bingham
S J Bolton
M J Carter
Ann Cleeves
Eva Dolan
Jim Eldridge
Kate Ellis
Jessica Fellowes
Lucy Foley
Elizabeth George
Isabelle Grey
Mari Hannah
Elizabeth Haynes
Harriet Lane
Colette McBeth
Dervla McTiernan
Louise Penny
Leigh Russell
Jo Spain
Dana Stabenow
Charles Todd
Julie Wassmer
I'm not a huge reader of crime fiction but going back to your original point TerriBull, the only names I know on that list are Ann Cleeves (from the Vera Stanhope and Shetland novels) and Elizabeth George so do the others deserved better recognition or do crime fans know these writers already?
One thing I like particularly about Who Else Writes Like? is that they include titles and writers suitable for young adult readers who are in the process of 'crossing-over' from reading books appropriate for children to tackling adult novels. A good thing.
