The team must dispose of a number of diictodons, cute-seeming but malevolent burrowing creatures who appear via an anomaly in a hospital, where they cause a power failure by biting through cables. Mick Harper, a nosey journalist, takes an interest in the team’s work. The diictodons are disposed of but Helen Cutter makes a clone of her husband in order to enter the ARC and find out more about an artefact she has stolen. SPOILER! SPOILER! SPOILER!A confrontation ensues after a bomb goes off, causing a fire, which, to all intents and purposes, claims the life of the real Nick Cutter. The team face off against diictodons, cute but surprisingly dangerous burrowing creatures that came through an anomaly from the Permian era that opened in the middle of a busy hospital in London.
