William Clemens directed this fourth and final cinematic outing starring Bonita Granville as Nancy Drew, John Litel as her father Carson Drew, and Frankie Thomas as her boyfriend Ted Nickerson. Here, two elderly ladies call upon Carson to help them after their chauffeur is murdered. The two ladies have been living in an old mansion for twenty years, and must stay another two weeks before they can sell it to be used as a children's hospital, but someone wants to stop them, and Nancy and Ted defy authorities to investigate. The best of the series, which uses more imagination in its story, though it still feels half-baked and too abrupt, coming up short, though the three leads(especially Granville) are fine, and could have made a fifth case, sadly not to be. This plot was used on the later(and unrelated) "Nancy Drew Mysteries" with Pamela Sue Martin called 'The Mystery Of The Whispering Walls'(Much better handled too.)
