Wells, Fargo"s detectives James B. Hume and John N. Thacker compiled a report of company losses between 1870 and 1884, but the report had another purpose. Within the pages, listing the exploits of 206 road agents, was a detailed physical description of each thus creating a textual mug book of potential recidivist robbers likely to victimize the company again. The report contained no details of the thrilling events which earned each robber a place in the report, but this work is intended to correct that shortcoming by giving all the details of over 400 stagecoach and train robberies, and a few burglaries, committed in half a dozen western states and territories.
