Of all the pictures the team sees, it's portraits that often prove the most intriguing. More often than not, there are two things that everyone wants to know about a portrait - who is it, and who painted it? Every day, the FAKE OR FORTUNE? team receives an email from someone who needs help solving a mystery. They sift through thousands of candidates in search of those precious few that have the spark of something special. The team often needs to unlock family secrets and carry out in-depth scientific research to get to the truth ... but how many stories will have a happy ending? This episode looks at three intriguing works of art. First we meet a retired couple from Eastbourne who share their flat with an 18th-century portrait of a beautiful young lady which may have been painted by society artist, Philip Mercier. Next, the British chief of a Dutch marketing firm wants to know if a sketch of a striking man with a shock of grey hair is by the greatest German artist of the 19th century, Adolph von Menzel. Finally, a Belgian couple with a passion for flea markets believe they may have stumbled upon a valuable early portrait by a colossus of modern art - Willem de Kooning.
