The third in Derleth's ""Sac Prairie Saga"", and once again a regional-historical meld with background material painstakingly dug out and worked in. This book tells of Hercules Dousman, a fur trader, who becomes the partner of Rolette, an agent of Astor's, and who falls in love with Rolette's pretty French wife. Out of loyalty to his partner he keeps his love well in hand, and most of the book deals with his fur trading activities among the Indians who are quick to flare up. He makes considerable money, a brief and unsatisfactory marriage, and finally after eighteen years marries his true love at his partner's death. I find Derleth consistently and carefully reliable, but equally laborious. I doubt if there is sufficient vitality in the tale to carry it beyond regional lines, Wisconsin and vicinity.
