This is book #11 and the last in the popular Derby Man series.
Darby Buckingham becomes the unwilling owner of a herd of twelve dirty and disagreeable camels. Deciding to go into the freight business, Darby is faced with unfriendly Paiutes, scorching desert and steep, impassable trails. Add to that the horrors contrived by the murderous band of a competitor, an ugly giant known as Big Bert Jasper, and you have all the makings of an exciting story.
