Kurkjian clearly knows how to work his beat — he won three Pulitzer Prizes while at the Boston Globe. For this book, he interviewed low-level criminals long suspected of the crime and he reached out to mob bosses for answers. And most impressive, he delivers the story of Louis Royce, who discovered the museum’s security lapses while sneaking into the galleries during his troubled teen years. Royce claims that he passed that information along to his criminal connections and that someone picked up his tip and carried out the heist. 

Placing the theft in historical context, Kurkjian charts the evolution of Boston’s gang wars in the 1980s and details how criminals have used stolen art to bargain plea deals. He also looks at the Gardner’s security issues, everything from troubles with the museum’s board to personnel lapses, and he examines failures in the FBI’s treatment of art crimes, building stark comparisons to more-successful European approaches. Notorious gangster Whitey Bulger’s story lurks along the edges of the narrative, and Kurkjian argues that Bulger’s capture in 2011 and the hunt for the Boston Marathon bombers in 2013 provide models for how crowdsourcing might be used to locate the missing Gardner masterpieces. Kurkjian has gathered so much information that explaining the smallest bit of it leads to a spate of cross-references, qualifications and digressions.
