ART INVESTIGATION TION Fake Or Fortune? 8pm, BBC1

AT AN auction in Chicago, Chuck and Kim Van Fossan bought a charming landscape they thought was by the great Impressionist painter

Alfred Sisley; however, a committee refused to authenticate it. If it were real, it would be worth £250,000, so there is a lot riding on this investigation into its provenance by Fiona Bruce and Philip Mould (pictured).
