Murder at the Gardner — Jane Langton

After a series of seemingly harmless pranks at Boston's Isabella Stewart Gardner Museum, the trustees call in ex-detective and Harvard lecturer Homer Kelly to investigate. But when art patron Madeline Hepplewhite is murdered after surprising the prankster, Homer has to answer questions a bit more pressing than "Who tied a balloon to the Cellini?"
