Summary

The group arrives at Chiswick House on a cold winter day. They split into two teams: James, Lucie, and Jesse search the gardens and greenhouse; Cordelia, Anna, and Ariadne search the house’s interior. In the gardens, James, Lucie, and Jesse find Jesse’s former tomb—a brick shed containing his open casket—which stirs painful memories. Jesse retrieves a hidden hand mirror from a false bottom in the coffin.

Meanwhile, inside the house, Cordelia, Anna, and Ariadne discover Grace’s bleak bedroom and explore a ballroom. A Gamigin demon attacks from a dumbwaiter; Cordelia tries to question it, but James, having sensed danger, kills the demon. They argue until Anna intervenes. Jesse and Lucie then reveal they found Tatiana’s hidden notes and a mirror in a chimney. James detects Belial’s aura on the mirror, confirming its demonic origin. The group decides to return to the London Institute to examine the artifacts.


Key Events

  • The party divides into two search teams at Chiswick House.
  • James, Lucie, and Jesse enter Jesse’s former tomb; James senses Belial’s presence and rushes back to the house.
  • Cordelia, Anna, and Ariadne encounter a Gamigin demon in a ballroom.
  • Cordelia attempts to question the demon; James shoots it, sparking a heated argument.
  • Anna de-escalates the conflict, scolding both for endangering the mission.

  • James identifies the mirror as having Belial’s aura; Lucie confirms it by touch.
  • The group decides to return to the Institute for further investigation.

Character Development

Cordelia feels helpless without Cortana and frustrated by her dependence on others. Her jealousy when Lucie touches James’s elbow reveals lingering romantic pain. She also shows compassion when asking Anna about Matthew, admitting she does not hate him.

James is protective and impulsive—he shoots the demon without questioning it, then argues with Cordelia. His inability to explain his actions (the Grace situation) widens their rift. He remains haunted by Belial’s influence.

Anna acts as both a peacemaker and a perceptive confidante. She gently tells Cordelia that James’s feelings may be deeper than they appear, and she warns Cordelia about Matthew’s fragile state.

Jesse confronts the horror of his past in the tomb but maintains composure. He keeps a secret learned from Grace, choosing not to betray her trust, which shows growth in loyalty and patience.

Lucie shows restraint by not pressing Jesse for the secret, demonstrating emotional maturity. She remains supportive and practical during the search.


Themes, Symbols, or Motifs

Communication breakdown – Cordelia and James argue without hearing each other; Cordelia refuses to ask James about what she saw with Grace. Anna’s advice (“things are not always as they first appear”) underscores the theme of misunderstood perceptions.

The weight of the past – Tatiana’s smashed mirrors and stopped clocks symbolize her frozen grief. Jesse’s tomb represents a life stolen by his mother’s cruelty. The house itself is a monument to neglect and bitterness.

Hidden truths – The hand mirror, the chimney cache, and the false-bottom coffin are physical manifestations of secrets. Belial’s aura on the mirror foreshadows his ongoing manipulation.


Why This Chapter Matters

This chapter advances the plot by introducing a powerful artifact tied directly to Belial, deepening the supernatural mystery. It also crystallizes the emotional conflict between Cordelia and James—her belief that he loves Grace, his inability to explain, and Anna’s revelation that James’s feelings may be genuine. The discovery of Tatiana’s notes provides a new investigative lead, while Jesse’s hidden knowledge about Grace sets up future revelations.


Study Questions and Answers

1. Why does Cordelia feel jealous when she sees Lucie touch James’s elbow?
Cordelia is hurt that Lucie is ignoring her and still feels deeply attached to James. The casual, affectionate gesture between Lucie and James reminds Cordelia of what she has lost, both her friendship with Lucie and her closeness to James.

2. What does Anna tell Cordelia about James’s feelings?
Anna says that when James looks at Grace, she sees nothing, but when he looks at Cordelia, his eyes blaze like a bonfire. Anna suggests Cordelia ask James what truly happened the night she saw him holding Grace, implying appearances may be deceiving.

3. What does the hand mirror reveal about Belial’s connection to Tatiana?
James senses Belial’s touch on the mirror immediately; Lucie also feels Belial’s aura when she touches it. This confirms that Tatiana was in league with Belial, and the mirror likely serves a darker purpose beyond being a hiding-place tool.
