Trouble in the Everglades

"When Tate Barkley meet[s] up with a man who calls himself "Gator" he doesn't know he's the boss of a gang of "plumers" - men who kill thousands of birds in the Everglades so their [plumes] can adorn fashionable ladies' hats. In fact, he doesn't even know what a "plumer" is. But he learns quick enough, and more about the rough and dangerous bunch than he ever wanted to know.
