Mabry's Challenge (Large type / large print ed)

In 1881, in a train robbery near Denver, Colorado, $500,000 in government greenbacks and gold was stolen, and two soldiers were brutally murdered.

All attempts by army and railway detectives to find the killers and recover the money ended in failure.

Then the Secretary of War's top advisor is told the man for the job is no-nonsense, relentless lawman Marshal Frank Mabry.
