Birds Of A Feather (1989)

As the Antiques Roadshow throws up a surprise for Dorien, a letter in an old box and a barmy Auntie Sylvie throw up a few shocks for Tracey and Sharon. What is the meaning of the letter?

Dorien brings round a piece of imperial silver to take to The Antiques Roadshow, leading them to rummage through the junk in the attic. Dorien uncovers an old box, but there's no key. Tracey is angry at them for routing. Dorien opens the box using her bracelet.

They find old love letters in the box written by their mother and an old flame, one of which mentions an orphanage. Sharon thinks she's adopted, Dorien thinks she's jumping to conclusions and tells her to ask Auntie Sylvie.

Tracey isn't pleased to find Sylvie in the house, she hates her perfume and she's barking mad, calling them by each others names. She gets annoyed that Sharon wants to ask her about her parents.

Sylvie sees Dorien's silver tea urn and tells her that she remembers them being sold on stalls in Hackney. Dorien snaps and tells her it is a genuine Russian antique.

At the Antiques Roadshow Dorien is all smiles when the expert starts examining her urn, he says it is Russian imperial silver, as he starts to estimate it's value his colleague interrupts and tells them it is in fact a copy, made during the war, just as Auntie Sylvie had said.

Back home Sharon confronts Sylvie with the letter, telling her to drop the barmy act. As Tracey gets upset, Sylvie rushes over and calls her by the correct name. She reveals that both of them were adopted and she had promised their mother on her death bed that she would not tell them. She also tells them that she faked their birth certificates when she worked at the town hall.
