The Witches of Karres
James H. Schmitz
 Captain Pausert, a well-intentioned, but inexperienced merchant traveler voyaging solo on the old pirate chaser Venture from the planet Nikkeldepain, is induced to purchase three young witches (Maleen, Goth, and the Leewit) who had been enslaved on the Imperial planet of Porlumma. The sisters were captured in a raid by Imperial slavers while visiting another planet on a jaunt of their own. In getting clear of Porlumma, the Venture escapes belated pursuit with the use of the witches' klatha (psionic) Sheewash drive, which enables far faster transit of distance than is possible with primary or secondary space drives available either in or outside the Empire. This draws the unwelcome attention of both the Imperium and other governments to both Captain Pausert and the elderly Venture. After returning the witch sisters to their homeworld, Karres, Captain Pausert attempts to return to Nikkeldepain, but is arrested before he can obtain permission to land. The Captain is informed that he faces a barrage of criminal charges, many relating to his encounter with the witches and his brief stay on the prohibited planet of Karres. And they want the Sheewash drive. Avidly. Captain Pausert escapes the Nikkeldepain police and military with the help of the middle witch sister, Goth, who had stowed away on the ship. From that point, he and Goth find themselves becoming more and more embroiled in wild adventures involving interdimensional alien invaders, space pirates, many more of the Karres witches, and assorted other characters.
