In the second episode, Fiona Bruce and Philip Mould head to north London to meet Glyn Hopkin, a car dealer with a soft spot for art.
He's taken a gamble on a painting he hopes is by a towering figure of 18th century art, Sir Joshua Reynolds. Glyn took a punt on this beguiling picture of a boy in a jacket at an online auction in Monaco, for £2,700. If it turns out to be genuine it could be worth £100,000.
The team arrange for Glyn's work to be examined by Dr Alexandra Gent, a Reynolds specialist and conservator at the National Portrait Gallery. Will Glyn's picture show similarities with authentic paintings?
The man making a decision on this complex work is the author of the most recent Catalogue Raisonné of Reynolds' work, Dr Martin Postle. Will Glyn's gamble pay off?
