kevinrutherford commented on Hollow Man by Carr John Dickson
In M W Craven's The Botanist, DS Washington Poe references John Dickson Carr a couple of times, so I also read The Hollow Man.
This is less a novel, more a pair of related logic puzzles. The style isn't really to my taste, but the resolutions are very satisfying. 4 stars (but only because I didn't get on with the prose style).
