Writing at the Golden Age Detection group on Facebook, Jeffrey Marks reminds us that today is the 126th anniversary of the birth of Fr. Ronald Knox, a classic writer from the Golden Age of English Detective Fiction. Father Knox is perhaps best remembered as the author of the "10 Commandments of Detective Fiction," a list which is frequently more honored in the breach than in the observance (including by Knox himself). (And a hat tip to Jeff for the link.)
I reviewed one of Knox's mysteries, The Viaduct Murder, on this blog several years ago including a full review on the podcast. It's an entertaining book, quite in keeping with the Golden Age tradition of fair play puzzles. It is still available (at the link) as an e-book for the Kindle, although I'm pretty sure it's out there in other electronic formats as well.
