pisode Three reveals that Mr. Walker's other woman is one of Sherman's wives.
As the gang now want £500,000, due to Barnaby messing up the previous phone call, they are getting desperate and decide to go to some actor to try and sell him the statue. They fail, however, due to Leah swapping it for a dog statue. They find out that Angel, the cartel's other son, is on his way to London. Barnaby and Nina go to a hotel looking for Leah and the statue which also involves a fight in a lift with what I'm guessing is a guy involved with the cartel that's looking for the "magpie"; which later turns out to be Leah. Nina figures out that he's someone to do with the cartel so beats him up and knocks him unconscious and puts him in the back of the car.
Mr Walker goes to meet the Sherman brothers and says he wants immunity and for them to pay for a house in Spain in exchange for not telling the cops that they're involved. Nina and Barnaby take the guy and Nina says she'll get rid of him by killing him, which obviously Barnaby isn't happy about so they argue about it on the side of the road. Meanwhile, Barnaby's car is rolling down the road and gets hit by a truck with the guy inside. They finally find Leah in a hotel room that she booked in her dad's name so they presume that Mr Walker is there too but he's not. Leah confesses that her dad asked her to work for him a year before and says Mr Walker was buying the statues for the Sherman's but they dropped out of the deal and because of that Mr Walker fell apart and left Leah to deal with it. She explains that she knew a drug dealer, the guy that Nina shot at the begining of episode one, and Leah did a deal with his cartel to sell the statues to them. They swapped the statues for drugs then bought the statues back and then payed Leah.
So following on from episode three, Nina, Barnaby and Leah arrange to meet the cartel's son Angel in a public area so a trip on the London eye it is then with a whole load of chinese tourists in tow. The "budgie smuggler", aka Barnaby, tells Angel they want £500,000 later that night for the statues or the deal's off. They arrange to meet somewhere quiet; a vip area in a nightclub. Later, the police get a call from a member of the WI saying they've won one of the statues in a raffle at the WI so when the three go to collect them they find that the cops have ceased them. They take the three in for questioning also DI Suleiman has worked out a cop is working for the Shermans.
The three hatch a plan to track down where the cops stored the statues to get them back. That fails so come up with getting the people that have the mothers who want money and Angel and his gang together so they all meet in the nightclub. Nina breaks into the gangs van to try and release the mothers. They do a deal between them that Angel gives the money to the gang, the gang release the mothers and Leah and Barnaby give Angel Nina in return.
