In this brand-new novella, Keller, everyone's favorite assassin for hire, is Chicago-bound on Amtrak's City of New Orleans, ready to do what he does best. But it's complicated. Usually there's someone ready to point him toward the target. Or he'll have a photo, say. Or, bare minimum, a name and address.

Not this time. When he gets to Baker's Bluff, Illinois, he'll have to play private detective before he can get down to business. Well, okay. He knows how it works. So before he boards his train, before he even packs his suitcase, Keller buys a fedora.

Keller, a faithful husband, doting father, and dedicated philatelist, has become a guilty pleasure for an increasing number of listeners. They don't think they should like the guy - but they just can't help themselves.
