Arthur Brut was a detective of art-related crimes before his journeys into the space inside paintings drove him insane. He was been locked in a mental institution ever since. But something terrible is happening in the art world- the Mona Lisa is seen winking, and people are being brutally murder by an Andy Warhol impersonator. Margot Breslin, now director of the Bureau of Artistic Integrity, must pull Arthur from his isolation to face the very problems that drove him mad. I enjoyed the many art history references, but could have done without the cheap cliff-hanger ending.
