Golden age mysteries that aren't the usual authors?

I know I just posted. My apologies.

I have read quite a bit of Agatha Christie, and many of the more obvious authors, so I'm looking for vintage mysteries (1950s, and earlier, lets say) by not so well known or maybe even obscure authors. Male or female will do, but for me as a female, female would be very interesting.

I've been reading interesting articles about bibliomysteries, my favorite mystery genre, besides cozy mysteries.

Do you know about the British Library Crime Classics series? Lots of good starting points there.

Let's see. I'm assuming Dorothy L.Sayers, Josephine Tey and Ngaio Marsh fall under the heading of "obvious authors", but if not, you could start there.

For series authors, you might try Elizabeth Daly. She wrote a series featuring Henry Gamadge, a rare book dealer. Agatha Christie admired her work. The first in that series is Unexpected Night.

For single books, I'd highly recommend Laura by Vera Caspary and The Unsuspected by Charlotte Armstrong.

>1 toast_and_tea: I just read and enjoyed the 1949 camp comedy murder mystery Poison for Teacher by Nancy Spain. It's part of a series but can be read as a standalone, although the publisher is also reprinting other books by Spain.

ECR Lorac is one of those that would fit. She also wrote as Carol Carnac

She has been re-released in the series in >2 thorold:

How about John Creasey or John Dickson Carr or Edmund Crispin or Margery Allingham

Obviously Allingham is the only woman on my list.

Patricia Wentworth -- the Miss Silver series and other series.

Mary Roberts Rinehart is another possibility, who I personally think is underrated.

I'm quite fond of Phoebe Atwood Taylor, in particular the Asey Mayo Cape Cod mysteries. I second pretty much all the above suggestions, too.

Gladys Mitchell is currently being reprinted in paperback. Her recurring character (it's a can be read in any order series) is an irascible crone genius with a degree in psychology and a passing interest in the occult.
