This week, art thieves made off with a Picasso and a Mondrian from Greece's National Art Gallery. So what's their next move? Art detective Richard Ellis is the man who tracked down Edvard Munch's "The Scream" in 1994, and is the founder of the Art and Antiques Squad at New Scotland Yard.  He is also  featured in a new book called Hot Art: Chasing Thieves and Detectives Through the Secret World of Stolen Art, by Joshua Knelman. We have two copies of Hot Art to give away, just send us an email at Day6@CBC.ca with the subject line HOT ART and your mailing address to be entered in the random draw.
