Goodbye, Ms. Chips — Dorothy Cannell

It's back to school for plump girl turned Thin Woman Ellie Haskell!

"The headmistress wants to see you." Words to strike terror in the heart of any inmate of St. Roberta's boarding school. Fortunately for Ellie, she is no longer a pudgy, wayward pupil but a happily married mother and interior designer with a beautiful home by the sea. Still, thanks to her success as an amateur local sleuth, Ellie has been summoned.

GOODBYE, MS. CHIPS
St. Roberta's needs Ellie's help now that the former games mistress, Ms. Chips, has retired. Could Ellie please come back on campus and find out who has stolen the Loverly sports trophy -- and is seeking to bring embarrassment to the school? Her less-than-rosy memories of being a student notwithstanding, Ellie cannot refuse headmistress Mrs. Battle's entreaties. Soon she finds herself in the thick of boarding school life, where an apparent schoolgirl prank gives way to murder.
