A round dozen, of which Colliers contributes 4, Ellery Queen's Mystery Magazine 3, and the SEP 2, the talent here is by no means unskilled and the representatives include some of the most practised professionals in the field. Particularly notable is Q. Patrick's story of a sight- seeing spinster and a mother-mad Mexican boy; Anthony Boucher's Retired Hangman and his one failure; Ellery Queen's George Washington whimsy; with Hugh Pentecost, Lawrence Blochman, John and Ward Hawkins among others that are familiar. The shorter form is here given smoother variations.
