If there is such a category as a guys' audio, The Whole Truth fits the bill perfectly. Ron McLarty's gruff voice enhances this fast-moving thriller as he takes the listener through barrages of deadly assaults featuring gunfire, knives, bombs and hacksaws. He portrays Shaw, the unwilling secret agent, as weary yet tough. Nicolas Creel, who needs a good war to help sagging profits, comes across as appropriately cerebral and coldhearted. While McLarty gives different accents to Anna and Katie, otherwise, both sound alike, but he performs a variety of French and Slavic villains in quick succession. The sound track is comparable to a terrific cinematic score: darkly foreboding or quietly romantic when appropriate, raising this audio to an art form and enhancing the already gripping tale.
