An exceedingly profane green parrot, with wicked glittering eyes and a genius for
 saying the wrong thing...A pretty (if rather prim) young librarian with a curious 
interest in dangerous weapons...An eccentric multi-millionaire, with a penchant
 for books, trailers and birds...An apparently un-traceable murder, committed with
 a double-barreled derringer, obsolete in design but deadly in efficiency... These,
 and some other bizarre details, which we won’t reveal, plunge Perry Mason and Della
 Street up to their necks in one of the most exciting mysteries that Erie Stanley 
Gardner has ever written!
