'Big' Jim Davis, as Matt Clark, Railroad Detective, traveled west each week to aid in the capture of one of history's notable badmen(or women). At times, Clark's appearance at the scene seems somewhat contrived, as in just "happening" to be in town when Ford shoots Jesse James. The stories do have some limited educational value, as each one sticks to the basic facts, although production values for the series were decidedly low budget. One thing I could never figure out...one week Clark would chase Quantrill in 1863, the next Tom Horn in 1903...30 years apart...yet he never aged!
