The 2018 Cloak and Dagger Challenge was hosted by Stormi @ Books, Movies, Reviews! Oh My! and Barb @ Booker T's Farm. I signed up at the "Amateur Sleuth" level (5-15 books) and actually read 15 books that qualified for the challenge. Didn't manage to get them all reviewed, but that's not unusual for me — I'll still be trying to add a few more reviews before the end of the year.
Books I read for the challenge (with links to reviews):
1. Intruder in the Dark (Chief Inspector Littlejohn #43). George Bellairs (1966; police procedural)Of the fifteen, I think my favorite was probably A Murder Is Announced — I love Miss Marple!
2. A Murder Is Announced (Miss Marple #5). Agatha Christie (1950; mystery)
3. Vintage Murder (Roderick Alleyn #5). Ngaio Marsh (1937; police procedural)
