Mule Man (Wheeler Large Print Western)

They called Brice Corrigan "Mule Man" because of the animal he rode, but they might as well have called him that because of his disposition. Hell, half of why he signed on to this godforsaken crew was because the lady who hired him suggested that he didn't have the guts to do the job. And an odd job it was. A crew of ten, led by an anthropologist, was going into Arizona's Chaco Canyon to dig for Anasazi relics. But even before they started digging, they started dying.
