Silver Blaze

"The Adventure of Silver Blaze", one of the 56 Sherlock Holmes short stories written by Sir Arthur Conan Doyle, is one of 12 in the cycle collected as The Memoirs of Sherlock Holmes. Doyle ranked "Silver Blaze" 13th in a list of his 19 favourite Sherlock Holmes stories.
One of the most popular Sherlock Holmes short stories, "Silver Blaze" focuses on the disappearance of the eponymous race horse (a famous winner, owned by a Colonel Ross) on the eve of an important race and on the apparent murder of its trainer. The tale is distinguished by its atmospheric Dartmoor setting and late-Victorian sporting milieu. It also features some of Conan Doyle's most effective plotting, hingeing on the "curious incident of the dog in the night-time":
Gregory (Scotland Yard detective): Is there any other point to which you would wish to draw my attention?
Holmes: To the curious incident of the dog in the night-time.
Gregory: The dog did nothing in the night-time.
Holmes: That was the curious incident.
