Loping along awkwardly, somewhat stooped, Tate was in a Brooks Brothers pinstripe beneath a yellow sou'wester and outrageous galoshes, having come here straight from his strip mall law office in Fairfax, Virginia, where he'd spent an hour explaining to Mattie Howe that suing the Prince William Advocate for libel because the paper had accurately reported her drunk-driving arrest was a lawsuit doomed to failure.

единственное, я поняла, что Prince William это округ Принс-Уильям в США, но что значит the Prince William Advocate?

заранее спасибо!
