"Is there any point to which you would wish to draw my attention?"

"To the curious incident of the dog in the nighttime."

"The dog did nothing in the nighttime."

"That was the curious incident," remarked Sherlock Holmes.

...

"...a dog was kept in the stables, and yet, though some one had been in and had fetched out a horse, he had not barked enough to arouse the two lads in the loft. Obviously the midnight visitor was some one whom the dog knew well."

The title of this book, The Curious Incident of the Dog in the Nighttime, actually references a story by Sir Arthur Conan Doyle titled "Silver Blaze."

Christopher references this short story because of his interest in Sherlock Holmes and the logic used in his mysteries. Why Christopher--who sees nothing but the logical in his life--would choose Holmes as a "hero"? Why is the reference to the story important?
