Fake or Fortune?

Can the team prove that a beautiful still life of a glass jug and pears is the work of celebrated British artist William Nicholson? Viewer Lyn asked for help because her painting was rejected by the leading authority on William Nicholson and was left out of the artist's latest catalogue raisonnee. Lyn bought the paining in 2006 for £165,000, believing it to be a genuine Nicholson, but now it's worth practically nothing. However, this damning ruling has divided art world opinion. Can Fiona Bruce and Philip Mould uncover enough new evidence to convince sceptics that this is a genuine Nicholson?

Fiona and Philip head to France to see if they can reverse an art world decision which one owner refuses to accept. Alain was given two sketchbooks by his grandmother back in 1965. Although she never revealed where they came from, they were thought to be the work of Toulouse Lautrec, the aristocratic artist born in 1864 known for his atmospheric depictions of Parisian nightlife. Alain waited 50 years before he decided to present the sketches to the French committee responsible for authenticating the work of Toulouse Lautrec. Unfortunately, the committee did not accept them as the work of Lautrec and stated they were the work of another artist - Rene Princeteau - meaning they are worth just a few thousand pounds instead of many hundreds of thousands. For Fiona and Philip, this is on one of their toughest investigations - they must not only discredit the sketches as the work of Princeteau but also persuade the committee to change their mind.

The team investigate whether a small watercolour sketch could be by the British 20th-century sculptor Henry Moore. It is the only piece thought to be a British artist in a Nazi hoard of around 1,500 works discovered in Germany in 2012. Known as the Gurlitt hoard, it is now housed in the Museum of Fine Art in Bern, Switzerland. Every piece in the hoard has to be researched, as if it was art stolen or looted from Jewish families, it should be returned. Fiona and Philip need to establish two things - firstly whether this a genuine work by Henry Moore or a whether it is a fake, And secondly, if it is genuine, how did a sketch by a British artist end up in a Nazi art hoard? The answer to this will decide it's fate.

Fiona Bruce and Philip Mould investigate two rare portraits of black British subjects from the 18th and 19th centuries. Painted with extraordinary skill and sophistication, both pictures are highly unusual in their positive depiction of black sitters at a time when Britain was still heavily engaged in slavery. But this is also an intriguing double whodunnit. Who are the artists who broke with the conventions of the time to paint these exceptional works?

Fiona Bruce and art expert Philip Mould investigate the first work of sculpture featured on the show, an unusual piece called The Gazing Head, which may have been made by Alberto Giacometti in 1930s Paris. The quest to uncover the truth is complicated by the fact that the sculpture was once broken into several pieces by a cat.
