There was then a further hiatus before it restarted, under a new publisher, on a monthly schedule, publishing a much wider range of detective and mystery-suspense stories (including some science fiction). After only ten issues, it changed its name to Mystery Stories, but only lasted a further two years before folding. The title was then acquired by Street & Smith and merged into Best Detective Magazine.
Although there were two British magazines called Mystery Stories, one was a British reprint edition of 15 Mystery Stories, and the other was a standalone series with no connection to the US magazine.
