Empty Coffins: Calvin Carter: Railroad Detective

When a group of bandits derails a train and murders an engineer in cold blood, it's not the loot they're after.
It's the coffins.
Debonair former actor turned railroad detective, Calvin Carter, is on that train. He zeroes in on the object of the robbery. From the clues left behind, corpses weren't the only things in the caskets. And a sniper's bullet silences the only witness.
Now, Carter may be the only player in this twisted script who can solve this Wild West mystery. But will he get to the truth in time, or end up in a pine box himself?
