This collection concludes with a previously and otherwise unpublished, privately owned Lord Peter Wimsey story!! And it's a good one, too. (Pre-Harriet, but with, inter alia, a spirited exchange between Peter and another young lady on the prevailing clichés about women.)
Woohoo!
On a largely unrelated note, I'm going to use this book for Genre: Suspense, not Darkest London (as I had originally planned) as my 15th extra square. Turns out that the settings are all over the place, from various parts of England to North America, with only a small part of the stories set in London -- too much of a stretch for a square named for that city specifically. Plenty of other books more noticeably set in London to fill the Darkest London square (which I'm still planning to do as well, though).
