This is a new edition of Arthur Conan Doyles classic mystery, The Hound of the Baskervilles. Its the same story. Mostly. That is, it contains the same characters, the same action, and much of the same dialogue.
Whats different? Well, its a little shorter, a little leaner, a little less verbose in some sections.
But the chief difference is that its now narrated by a dog. A greyhound, in fact, named Septimus.
In this new edition, he tells his story of how he became The Greyhound of the Baskervilles.
