From the jacketflap:
This is the first of an annual series of Ellery Queen anthologies including only stories that have never before been published in the United States. Most of the stories have never previously been published anywhere.
Featured are a short novel by Patricia Moyes, called by The New York Times "One of the brightest contemporary practitioners of the classic practitioners of the classic puzzle-and-plot whodunit," and 15 short stories by such international favorites in the mystery genre as Christiana Brand, about whom Anthony Boucher said, "You have to reach for the greatest of Great Names to find Brand's rivals in the subtleties of the trade"; Edward D. Hoch ("Hoch has imagination and a comic bent" - Publishers Weekly); Seicho Matsumoto, the acknowledge most important figure on the Japanese detective-story scene today; and Joan Aiken, whose stories, wrote Carol Cleveland in Twentieth Century Crime and Mystery Writers, "flash with wit, and fantasy, and the peculiar wisdom of this very individual writer."
This collection leads off with a fine Sherlock Holmes pastiche and follows through with a prime mix of mystery and detection, some of it very light-hearted, some of it very dark indeed.
