Tishomingo Blues is Elmore Leonard’s thirty-seventh novel. At that number you’d think he’d be flagging, but no, the maestro is in top form. If, like Graham Greene, he were in the habit of dividing his books into “novels” and “entertainments”—with, for instance, Pagan Babies and Cuba Libre in the former list, and Glitz, Get Shorty, and Be Cool in the latter—this one might fall on the “entertainment” side; but, as with Greene, those that might be consigned to the “entertainment” section are not necessarily of poorer quality.
