In the opening scenes a body is found in a London sewer; this isn't a case for UCOS but the officer in charge; Sasha's ex-husband, DAC Ned Hancock thinks there may possibly be a link to the murder of another man twenty years previously. The two had been involved but given the time separation a link between the murders seems tenuous
till Danny points out there is a link. The early victim was drowned in a stream which is the headwater of the River Fleet which disappears under the city where it is a sewer; the sewer where the later victim was found. As the team investigate further they find that the two men were involved in an occult group that believed that the Fleet had some sort of mystical power. The main clue is an old film; however it is incomplete and they believe the missing section will tell them why the crimes took place. The fact that the case was given to UCOS by Sasha's ex-husband leads to confrontation between the two investigations although it is clear that his investigation is going nowhere while UCOS make all the running.
This was an enjoyably episode despite the somewhat unlikely premise it seems every murder mystery series must have an episode dealing with followers of the occult. Danny's explanations of the history of the Fleet managed to be interesting without feeling like we were being given a history lecture. There aren't too many suspects and I'm sure most viewers will figure out what happened a fair time before the final reveal; that doesn't spoil the enjoyment though it just means the viewer who figures it out can feel a little smug! The tension between Sasha and her ex is a bit of a distraction although it is satisfying each time she gets the better of him. The cast do a pretty good job; I have certainly got used to the newer team members faster than I'd expected. Overall a pretty good episode.
