In this one, there is murder and there is mystery. But, true to this series, these aren't front and center. The war-damaged Ian Rutledge confronts other damaged characters in post-WW1 England and Scotland, both countries also suffering from so much loss. And like in any good cozy murder mystery, there are red herrings, suspicious characters, a village, a huge country manor, and all other accouterments we know and love. Is there enough information to allow one to guess the villian(s)? Perhaps not, but the mysteries are piled high, many are resolved, and we get a classic cliff-hanger! I have the fifth one, "Watchers of Time" here in my home office and it's eyeing me now, but I'll resist and read a few other works first, enjoying the anticipation. (By the way, the story of England recovering from WW1 and then gearing up for WW2 is best captured, in my opinion, by Anthony Powell's incredible "A Dance to the Music of Time" and I recommend reading all 12 novels of "Dance" in order. I read them last year, about one a month, for a truly rewarding experience.)
