Nikki and Jack , joined by the apparently decent Dr Jenkins, unearth more bodies, leading to Niall being rearrested. Steve Boyd reports girlfriend Sarah missing, revealing to Jack what she had told him about her previous ordeal, whilst Jason Ross admits to Nikki he called her in because he felt that in the past Jenkins had colluded with Mac Neil and Laing to falsify evidence. In fact Jenkins confesses to Nikki that he had been forced to lie because Laing spent most of his time covering for loose cannon MacNeil and needed his help. The pathologists return to the Manhattan and learn that almost all the victims had worked there, including, very briefly, Sarah. As a result Stella makes a phone call to Laing regarding her son Jerome. Laing finally confesses to Nikki, Jack and DS Ross about his relationship with Stella, which consequently leads to them finding Sarah and identifying the serial killer.
