Fake or Fortune? — Season 12

In episode one, American artist Jeffrey Kroll believes a picture he inherited depicting a delicate chrysanthemum flower is by one of the pioneers of abstract art, Piet Mondrian.The provenance is encouraging, with many labels on the back of the picture from prominent Dutch art collections. The trouble is, forgers have gone to great lengths to copy Mondrian's work – can the team prove that Jeffrey's is a genuine picture by the Dutch master?

This week art detectives Fiona Bruce and Philip Mould set out to discover if a beautiful painting of women working in a field could be a valuable lost work by Helen McNicoll, a celebrated Impressionist artist from Canada.The quest to prove it takes the team to Toronto and Quebec City in search of answers and brings them into the orbit of billionaire art collector Pierre Lassonde, who knows McNicoll's work intimately. Has owner David discovered a long-lost work by a pioneering female artist?

The team take on an entertaining new challenge when they plunge into the fast-growing market for rock music memorabilia. Can they prove that a curious silver guitar once belonged to Ronnie Wood of the Rolling Stones - and could a baby grand piano now owned by 90s pop star Chesney Hawkes, have once belonged to John Lennon of the Beatles?It's an investigation that leads them to some colourful characters from the 1970s music scene, but with memories very hazy in the era of the Beatles and the Stones, can the team get any closer to the truth?

Fiona Bruce and Philip Mould investigate a lovely landscape painting, purported to be by one of the forefathers of impressionism and one of the most important artists of the 19th century, Jean-Baptiste-Camille Corot. Its owner, Sally Green's late husband, bought it in the late 70s, primarily for the impressive frame. He was always intrigued by the painting and wondered if it was genuine. Sally is now on a mission to finish what he started. However, the painting was turned down by the authority on Corot, so the team will have to find new evidence to help persuade them to change their mind. A lot is at stake. If the work is genuine, it could be worth £70,000. If not, just a few hundred.
