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.
Miranda Davenport was born in about 1950. She grew up to become a snooty lady who ran an antique's shop. She made her money by obtaining things by slippery means.
In "Yesterday Never Comes" 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 went to visit Miranda whilst she was at an auction. Davenport was embarrassed by Del's appearance, asking him to leave and promising to meet him later. As Del made his way out, however, a new item was placed up for bid. It was the very portrait had given her.
The painting it transpired was worth thousands of pounds. With the game now up, Miranda gloatingly told Del that she had recognised its true value straight away and only pretended to like him, so she could her hands on it. When Del tried to talk to her about this, Miranda told him firmly and smugly that the painting was hers. She had already registered the picture in her name and had even gotten her parents to an affidavit, swearing that the painting had been theirs for generations.
For a moment, it looked as if Davenport had successfully managed to swindle Derek and his family out of a small fortune. However, Del Boy soon turned the tables and ultimately managed to get the last laugh. To Miranda's confusion, Trotter is completely relieved to learn all of this. It turns out that he knew all along who had painted that picture and was fully aware of its true value. Miranda is initially dismissive of this, going so far as to sarcastically remark "How could someone like you possibly know that?"
Prompted Del tells her the answer. He knows because his grandmother, Violet, worked as a cleaning lady for an art dealer. However, she did not have the painting examined as Miranda initially believes, oh dear no. Instead, dear old grandmother, Violet Trotter, stole the painting!!!
Miranda's joy immediately evaporates at this revelation. She turns away from Del and looks back at the front of the auction room in horror as the painting is purchased, having learned far too late that she is, in fact, selling stolen property. With their position's now reversed, the triumphant Del Boy sarcastically wishes his fickle ex-love-interest good luck. He gives the deflated Miranda a parting kiss and the small bouquet he had originally brought for her. Knowing that the painting can never be traced back to him or his family, Del adjusts his collar then marches smartly out of the auction room, abandoning Miranda Davenport to her fate as two men begin to examine the painting's authenticity.
In his 2015 autobiography, He Who Dares, Del revealed that following the auction, Miranda was investigated. When several other suspiciously acquired items were uncovered in her shop, she was arrested and spent an unspecified amount of time in prison.
