François Picard is pleased to welcome art crime detective Arthur Brand. "In the old days they stole a painting, but a painting is unique; you cannot cut it in two," explains Brand, "In the last 10 years they have been targeting more and more objects made of gold, silver". He examines the transformation of international art theft, warning that increasingly sophisticated criminal opportunism is shifting attention from irreplaceable paintings towards precious metals and gemstones that can be dismantled, melted down or dispersed.
