- Narrator: The great Allen Pinkerton won fame as Chief of secret services for Union armies during the Civil War. After that, the detective organization he headed became the scourge of outlaw gangs on the Western frontier. But sometimes, the Pinkertons failed to notify local peace officers of their activities and it was this neglect that brought Pinkerton into conflict with Wyatt Earp. Their mutual enemy was the Crummy Newton gang of train robbers and neither Earp nor Pinkerton would afford to quarrel. Not with Crummy Newton and his men riding toward Wichita.
