The big tawny dog named Smoky refused to hunt with the pack, so old Bill Tolliver gave the "no-good hound" to Tome Rainse, the new Game Warden. Tom discovered that Smoky's keen bloodhound nose tracked men, not animals, and soon he was hot on the trail of a ring of poachers whose mysterious leader was called "Black Elk." These illegal hunters swore they'd kill anyone who got in their way, and now Warden Tom had a special partner who could smell trouble coming.
