In the August email from the Crime Classics folks (UK), they mention that the Allingham Casebook, a "collection of witty short stories", by (surprise) Margery Allingham will be on sale for $0.99 on August 17, tomorrow. However, just for fun I looked today, and found that it has already dropped at Kindle US.
It does not seem to be available at either Kindle UK (can't find a Kindle edition, odd, since Crime Classics is a UK thing, I thought, but I know the rights are very different for Allingham's titles in the US and UK) or Kobo US (can't find it at all).
I also don't know if this is the same collection of stories as
The Case Book of Mr. Campion listed at SYKM, and I'm in a hurry so don't have time to check. If someone else knows the answer or has time to investigate, please share your knowledge!
Anyway, here are link and blurb:
