Just the Facts, Ma'am 2019 Signup

Since I've just read the last book for my 2018 Just The Facts, Ma'am Challenge I figure nows the time to sign up for the new year. This is a challenge to read vintage mysteries of either the golden age or the silver age (or both!) hosted by Bev at My Reader's Block. Full details are given here.

I'm going to sign up at the constable level for both the gold and silver eras, though given my usual reading habits I suspect I'll do better than that.

Thanks, Bev, for hosting!
