Robert and Ravi pursue Jack but the parasite known as the reaper bursts out of him and into Ravi. Robert is grateful to the medically trained Lily for lending him an X-ray machine to locate the bug but must destroy it before it takes over his brother's brain. With Bella's help he lures Bulstrode to the music hall and, using Hyde's blood and monocane, forces the Reaper out of Ravi and thus finds a way to coerce Bulstrode into leaving him alone. However Bulstrode's department soon finds that there is another deadly menace in town.
