Tales of the Black Widowers is a collection of mystery short stories by American author Isaac Asimov, featuring his fictional club of mystery solvers, the Black Widowers. It was first published in hardcover by Doubleday in June 1974, and in paperback by the Fawcett Crest imprint of Ballantine Books in August 1976. The first British edition was issued by Panther in 1976. The book has also been translated into German and French. This book is the first of six that describe mysteries solved by the Black Widowers, based on a literary dining club he belonged to known as the Trap Door Spiders. It collects twelve stories by Asimov, nine reprinted from mystery magazines and three previously unpublished, together with a general introduction, and an afterword following each story by the author. Each story involves the club members' knowledge of trivia. Source: Wikipedia (en)
