In the 1950s, acclaimed SF authors Silverberg and Garrett wrote mystery-themed short stories under the joint pseudonym of Robert Randall, and seven of them are collected in this engaging volume. All the stories are well-written and display the imagination evidenced in the author's individual work. There's something for most tastes, including the hilarious "The Mummy Takes a Wife." For many readers the high points will be the three tales mixing science fiction, mystery and theological elements. In "No Future in This" and "Deus ex Machina," the discovery of a device that can predict the future places a great moral burden on Father Sean Riley, who's uniquely able to use it. Father Brown fans, and those who remember Anthony Boucher's Sister Ursula stories fondly, will be delighted by the title story, in which Sister Mary Magdalene must solve the murder of an alien. Both SF and mystery readers will hope that more of these tales will be reprinted in the future. Copyright Reed Business Information, a division of Reed Elsevier Inc. All rights reserved.
