Kempton Bunton, an elderly gentleman, claimed he executed the theft armed with only a toy gun, a disguise purchased for five shillings, and a getaway car inadvertently provided by a drunkard. Shortly after turning himself in, Bunton also invoked language in an obscure law to maintain his innocence, despite the confession. He did not allege that the confession was false, but rather that stealing the painting did not constitute a crime because he intended to return it. On account of this improbable defense strategy, the story took another twist, resulting in a bizarre courtroom drama and extraordinary verdict.
Over fifty years later, Alan Hirsch decided to explore the facts behind this historic case and uncovered shocking new evidence that both solved the crime and deepened the mystery. As Hirsch immersed himself in court documents, National Gallery archives, press accounts, and previously unseen materials belonging to Kempton Bunton, and interviewed several people involved in the theft or trial, he managed to solve the legendary crime that riveted a nation.
