The quality-level of the Ellery Queen anthologies seems to be falling off as their frequency rises. There were three last year, two of them duds; and this new one offers little reason to hope for an upswing. Again the novella is by Hugh Pentecost--though this one (about a ""Mr. Big"" taking over the world) is a bit more readable than some of the Pentecost mass-productions. And again there are fewer stories than heretofore--18 this time--with not a single gem in the bunch. Among the better entries: an amusing bit (about palindrome-induced murder) by Charlene Weir; some Berkely Mather adventure; an EQ ""Puzzle Club"" short-short; under-par work by Joyce Harrington, Patricia Highsmith, and Victor Canning; and an H. G. Wells oldie. With an unfortunate emphasis on whimsy, parody, and such (e.g., a mystery in Oz with Dorothy et al.)--an eminently skippable collection.
