In The Hollow Man, some thinly characterised people try to work out a locked room mystery, probably less paper-thin than they seem for some readers since it’s actually the sixth or so entry in a long running series, but really not sufficient for someone just starting out. Various implausibilities are discussed, unlikely red herrings crop up, and in the end there’s a shocking reveal, the trick is explained, and no one of any consequence to the reader has changed or grown at all.
As a puzzle story, it’s not bad, but I don’t quite get the hype about John Dickson Carr if this is typical of his work. It feels like the story and characters are thin layers of papier-mâché covering what the author really wanted to do, which was just play with that puzzle. It’s not unusual for a Golden Age crime novel, but from the enthusiasm of other readers I assumed there would be more to it than this. I’ll probably try another book or so by Carr — series detectives like his Gideon Fell can be a difficult proposition, but other books not featuring this character might be okay (reader, I hate Poirot, but Agatha Christie is really not bad when you leave him out of it). This wasn’t bad, I just didn’t care.
