Smith is called to the scene of an arson attack inside the remains of a derelict cinema, but soon discovers the body of a badly burnt victim inside, which is soon identified as that of Manisha. Morrell takes over the investigation and immediately places Peter Baxter in the frame. However, with very little evidence to prove any form of guilt, Morrell and Nixon realises that his knowledge of the local area may prove usual in finding the killer. Meanwhile, new CCTV footage discovers that Manisha did not board the bus that the previous CCTV indicated, and that she hailed down a nearby cab. However, before Nixon can warn De Costa, she already finds herself in the back of the suspect's cab. (thetvdb.com)
