These stories, written by the late Harold Lamb, appeared in the old Adventure magazine from 1916 to 1926. They are based on the innocently heroic saga of two Cossacks, Khlit and his foster son Kirdy, from the reign of Ivan the Terrible to the early seventeenth century. Khlit, ""the Wolf,"" is a canny old fox who has survived much longer than most. In the opening story he bets his life's fortune that his foster son will arrive at the village performing a feat of daring that surpasses any that have gone before. . . then he proceeds to insure that he will by a clever trick. Later Khlit singlehandedly takes on a Tartar horde and strategically decimates them, and as an outcast from the Cossacks who have tried to retire him, he joins the Tartars, kills an old nemesis and starts an unexpected war. Still later ""in the year of the ape"" he joins ""the Golden Horde"" becoming a legendary leader. . . . ""By the god Fo,"" there is much glory for those who like the steppes leading up to it.
