Eve Myles as DS Lola Franks and Babou Ceesay as DI Jackson Mendy.
(Warning - contains spoilers!)
Freddy (Hermione Corfield) and Baba (Dipo Ola) have fled the city in search of an isolated spot to bury Darren Cork (Neil Stuke), witness to their murderous night in the woods but tensions flare when the "dead" man rises again from the boot of the car and attempts to flee.
Dipo Ola as Baba.
Freddy is for killing him all over again - he's seen their faces after all - but Baba rebels. The steely-eyed killer is not used to missing his mark, and he takes Darren's resurrection as a sign from God that he should stop this killing while he still can.
In London, Jackson (Babou Ceesay) and Lola (Eve Myles) are working their way through Matt Bowers' (Tom Andrews) address book.
His lover and business partner are doubtful about his apparent suicide, so when they find Freddy in London (exorcising her anger over Baba's weakness) they take the opportunity to question her again.
Freddy (Hermione Corfield) is interviewed by DS Lola Franks and DCI Jackson Mendy.
Lola is sure she's guilty, but back at the station DSI Susan Smart (Vicki Pepperdine) is not convinced. There's no evidence that Freddy was capable of killing anyone and a murder-suicide ties up two cases with a neat little bow - the case is closed.
And then Jackson and Lola make a late breakthrough over a cup of green tea...
