Dorothy Salisbury Davis is a first-rate American author - one who, happily, is nearing her 98th birthday. The e-book publishers at Open Road Integrated Media just announced that 22 books by Davis - 21 novels and an anthology of short stories - are being made available as e-books.
I am not all that familiar with Davis's work - much of it done in the 1950s and 1960s - but she is very widely regarded as one of the leading American mystery writers, having received the Grand Master Award from the Mystery Writers of America, not to mention lifetime achievement Anthony and Agatha awards from Bouchercon and Malice Domestic respectively.
The one work of hers that I have read recently is the short story "Lost Generation," which was included in Sarah Weinman's recent anthology, Troubled Daughters, Twisted Wives. It is a profoundly disturbing and powerful story, and I do recommend it. I believe it is also contained in the anthology, Tales of a Stormy Night, which is one of the books being republished by Open Road. You can find most of them on her Open Road author page.
I have said many times that one of the things I hope will be accomplished by the widening availability and acceptance of e-books is the return to "print" of a great many fine authors in all mystery genres, for the enjoyment of a new generation of readers. It's a goal I'm happy to see being achieved by Open Road.
