Tom's alleged mother, Sophia, appears on the premises and helps Claire escape her locked bedroom. She tells Claire how Klein and Utterson had indeed tried to clone Doctor Jekyll but had been unsuccessful. Claire meets several of the failed attempts in the lowest basement of the building. They are disfigured and in a near-vegetative state. Sophia explains that Jackman is a descendant of Doctor Jekyll, (who died a virgin), through Mr Hyde, and by chance a perfect natural genetic duplicate, "a perfect throwback, a chance in a million". Klein and Utterson had discovered this and had him under surveillance for almost his entire life, from when he was six-months-old. In order to trigger his transformation into Hyde, they created a clone of Alice, the maid whom Jekyll had loved. This clone is Claire herself.
