<P> As the Trotters are enjoying another evening at The Nag's Head, Boycie and his business partner Abdul call Del Boy in for a secret meeting, with a proposal that he travels to Amsterdam to buy some diamonds and bring them back to England, without informing Customs and Excise . Realising that this is smuggling, Del rebuffs Boycie and Abdul, but is quickly swayed when Boycie offers him £ 15,000 for his efforts . </P> <P> The next morning, as they arrive at the market, Rodney is worried that the diamond smuggling trip is far too risky, but Del assures him that everything will be fine . Just then, Denzil shows up in his lorry, and informs Del that Corrine (Denzil's wife) made Denzil promise to keep his distance from Del . (This links in with a sub-plot in which Del is seen to "haunt" Denzil .) With all that said, Denzil drives off . </P> <P> The Trotter Brothers quickly run off from the police after trying to flog watches that play 36 different national anthems, but they run into local policeman DCI Roy Slater and his partner DC Terry Hoskins . At Sid's cafe, Slater tells Del and Rodney that he is investigating the case, and already knows that Boycie and Abdul are involved, but doesn't know who the courier is . Also, Slater mentions that he'll be retiring from the police force after solving the case (though Hoskins earlier explained that Slater was being forced out due to his corrupt nature). As Slater and Hoskins leave, Del phones Boycie and warns him that Slater's investigating them . Boycie suggests that they and Abdul meet up tonight, and Del knows the perfect meeting place . </P> <P> That night, as Boycie and Abdul wait in the trailer of an unsuspecting Denzil's lorry in a car park, Del and Rodney arrive in the Trotter van . With Rodney standing watch, Del enters the trailer and receives the diamond payment briefcase from Boycie to take with him to Amsterdam . Boycie and Abdul leave, and Slater shows up, having received a call from a nearby resident . Del prepares to exit until he sees Slater searching the area, and hides under a tarpaulin at the far end of the trailer . He is not spotted, but Slater inadvertently locks him in the trailer, before Denzil arrives and drives off . In desperation, Rodney sets off in pursuit, eventually following Denzil to Hull . Back at the station, Slater orders that a watch be placed on Boycie and Abdul's movements, and has a discussion with Hoskins about the possible courier, with Slater mentioning that the Trotters have not been seen for a few days . Despite laughing off Hoskins' suggestion that the Trotters could be the couriers, Slater mentions that Del is more intelligent than he lets on and would know the ins and outs of the world . </P>
