After a series of seemingly harmless pranks at Boston's Isabella 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?"

"Langton tucks her tongue firmly in cheek before treating readers to a wild and wholly enjoyable ride on the trail of the dangerous trickster...An exceedingly charming mystery." (Publishers Weekly)
