Jay McGraw's job might not have been too exciting, but it was a steady one. He was a messenger for Wells Fargo, and guarding its famous treasure box was his responsibility. Usually it was a fairly routine business ... but one day trouble came his way. Not long into the run between San Francisco and Chicago, masked bandits blew up a key bridge on the trail. Jay knew right away what they were after. If the bandits had their way, Wells Fargo would lose its shipment--and Jay would lose his job. But Jay wouldn't give up without a fight . . .
