Episode 11

Andersen heads out onto the glacier in an attempt to rescue Morton. In a flashback to the night of Pettigrew's death, Andersen reveals to Morton that he found Pettigrew in Elena's hotel room, attempting to rape her. Having subdued him, he then took Pettigrew out to the beach and handcuffed him to a pylon, where he subsequently mauled by a polar bear - before being shot by Henry Tyson. Meanwhile, Rattrey goes in search of Stoddard's dog, who was shot at the scene of his murder. A post-mortem examination reveals the dog to have ingested Larvae that was found in Morton's remains. Suspecting that Dr. Allerdyce became the Larvae host, transferring them from Liam Sutter to her daughter, he finally uncovers the link between the two murders. But on attempting to uncover the Larvae identity, he finds Dr. Allerdyce's body has become a feeding ground.
