While we can be thankful for real-life developments in forensic science that enable the speedier detection of criminals, there can be little argument that it was the death-knell of good detective fiction. Dull Inspector Arnold and his genius amateur sidekick Desmond Merrion spend so much time combing through the minutiae of the physical and mental aspect of the crime in Death in the Tunnel, and come up with such entertaining possibilities while doing so, that a crime scene tech in one of those all-over white body suits could never be a fifth as much fun. It makes me all the more appreciative of this kind of classic approach, knowing that this sort of book has seen its heyday pass.
