The Night Horseman 

For all his untamed ways, Whistling Dan Barry has won the love of Kate Cumberland, who struggles to lure him from the call of the wind and the night in the desert country. But Dan’s mysterious personality leads him into one difficult situation after another, for the path he takes with his wild companions – the stallion Satan and the wolf dog Black Bart – is strewn with desperate enemies and fierce encounters. „The Night Horseman” is part of a trilogy about a mysterious gunslinger who appears to be a ’Casper Milquetoaste’ but, in concert with a powerful wolf-dog, and a murderous stallion; is able to overpower seemingly any opposing force.
