The Mystery Writers of America combine, once again, to reflect modern times and it's hard to say who's the ugliest of them all since there are eye-to-eye confrontations with drugs, racism and violence on the urban underside of Amerika. About a third of the stories are by relatively little known writers -- two have not been previously published -- and the most chilling include Joe Gores who always comes on strong, Robert Bloch's ""Untouchable"" frisson, Edward Hoch's Edgar-winning ""The Oblong Room"" and Stanley Ellin's ""The Question"" which you've read before and you will again even if you haven't forgotten a word of it. Lots of professional, decisive present shock.
