Query: Decent story ruined by an awful ending

Patricia Ann and Mary Alice are sisters and complete opposites. But when the man who sold Mary Alice a C&W; bar is killed there the next night, the sisters find themselves trying to prove the murderer is not one of Patricia Ann's former students.Surprisingly interesting, since Mary Alice is an overbearing know-it-all and Patricia Ann lets her dictate large chunks of her life. But it kept me reading up to the awful deus-ex-machina ending and explanation that mostly relied on information that had NOT been given to the reader, which bitterly disappointed me and is the reason for the low rating.
