Fake or Fortune?

In episode three, Fiona Bruce and Philip Mould head to France on the trail of two of the greatest Impressionist and Post-Impressionist artists, Camille Pissarro, and his friend and protégé, Paul Cézanne.

Fiona travels to the stunning Provençal landscape on the trail of a simple watercolour, owned by Dominique Rogers. Dominique is the great- great niece of Anthony Valabrègue, a poet, art critic and friend of Cézanne who painted him several times. Dominique believes the painting was a direct gift from Cézanne, passed on by Valabrègue's widow to her father in the 1920s.

Meanwhile Philip travels to Pontoise in northern France, where Pissarro set up home, to meet Zana Glaser, who inherited a drawing depicting a group of cabbage sellers from her father, Tom. It was accepted that the outline of the drawing and signature were by Pissarro, but when Tom tried to sell the drawing at auction in 2012 it was rejected by the Pissarro committee who felt it had been coloured by another hand. Zana turns to the Fake or Fortune team for help. Can science prove that the outline and colouring were done at the same time?

If the Pissarro is genuine, it may be worth as much as £50,000. If not, its value is probably no more than £1,000. And if the Cézanne is authenticated, it could be worth a massive £100,000 as the artist's work has never been more popular. If not, it's worth virtually nothing. Can the team gather enough evidence to persuade the relevant authorities?
