Miranda Davenport was a one-off character who appeared in "Yesterday Never Comes". An antique dealer, she got close to Del Boy Trotter after he tried to sell her what he believed to be antique furniture. However, Miranda instead took a liking to a painting in the Trotters apartment, and eventually persuaded Del to give it to her.
At the end of the episode, Del found Miranda at an auction, where he learnt that Miranda had put the painting up for sale in order to make a massive profit. The painting it transpired was worth thousands of pounds, and Miranda having recognised its true value straight away, only pretended to like Del Boy in order to get her hands on it. When Del tried to talk to her about this she smugly informed him that she had already registered the painting in her name, and had even got her parents to sign documents swearing the painting was in their family for generations.
For a moment it looked as if she had successfully managed to swindle Del Boy, but ultimately Trotter had the last laugh. Much to Miranda's shock, he was completely relieved to learn all of this as it turns out that he knew all along who painted it and how much the painting was worth. Miranda is initially dismissive of this, going so far as to sarcastically remark "How could someone like you possibly know that?" Del promptly answers that question; he knows because his grandmother worked as a cleaning lady for an art dealer, but didn't have the painting examined as Miranda originally assumes...
...Dear old grandmother Trotter stole the painting!!!
Any joy that Miranda has been feeling promptly evaporates. She turns around and looks on in horror as the painting is bought, at the realisation that she is, in fact, selling stolen property. Their position's reversed, Del sarcastically wishes her luck, as he gives her a parting kiss and some flowers. Knowing that the painting can never be traced back to him or his family, he then walks smartly out of the auction room, abandoning Miranda to her fate as two men begin to examine to painting's authenticity.
In the 2015 novel, He Who Dares, it was revealed that following the auction Miranda was investigated, and when several other suspiciously acquired items were uncovered in her shop, spent an unspecified amount of time in prison.
