Attacks on churches and synagogues threatens to break the fragile peace between Whitechapel's religious communities. Bella Drake's 'uncle', Gabriel Cain (Paul Kaye), a charismatic scholar with a group of fanatical followers of his unorthodox occult beliefs of Elizabethan astrologer John Dee seek to convert Drake. Rose Erskine, seeking financial help from penniless Long Susan, falls foul of the same group. Reid is astonished to find a photograph of Bella as Cain's holy queen and pregnant. Tragedy befalls Drake when he, Bella, and Rose are brought together to take part in the groups intention to commit mass suicide.
