The Suspicions of Mr Whicher

* Thirty-two years later, in the Sherlock Holmes short story 'Silver Blaze' (1892), Arthur Conan Doyle referred to 'the curious incident of the dog in the night-time', the curious incident being that the dog did not bark when he encountered an intruder, and the solution to the riddle being that the intruder was known to the dog. But the Road Hill murder, being fact rather than fiction, had messier, more ambiguous clues: the dog did bark on the night of the murder, but not a lot.
