From the back of the 208-page hardcover book:
"The Marshal's Handbook is the gamemaster's guide to the world of Deadlands: The Weird West. It tells you how to rope those broncos into your adventures and keep 'em on the run from the insidious horrors of the Weird West. This book is packed with all the handy rules you need to strike an intrepid posse insane with fear, stop a foolhardy huckster dead in his tracks, and drive an almost-mad scientist straight over the edge.
It's also got a whole passel o' nasty critters to throw at those do-gooders, all drawn up in living-well, undead-color. Plus stick around for the lowdown on the best ways to torment those heroes who just won't stay dead-the Harrowed-and find out exactly what those manitous squirming around in their rotten insides are up to. If you're good, we might even tell you what the Reckoners are up to and give you a guided tour of their horrific handiwork throughout the Weird West."
