Tunnel of Bones Part 4 Summary & Analysis

Part 4: “Mayhem”

Part 4, Chapter 17 Summary

Content Warning: This section of the guide includes discussion of death and child death.



Through her camera lens, Cassidy can see Thomas’s red glow on the dark train. She enters the Veil, despite Jacob’s warnings. The ghost of that Veil threatens her, but Jacob pulls her to safety outside the stopped train. They hear Thomas counting in French. He appears when Cassidy says “please” in French, but only briefly. Suddenly, the train begins moving again. Cassidy and Jacob exit the Veil, and Cassidy stumbles while trying to get back on the Metro, but Jacob grasps her hand and helps her up.

When they find Pauline, her discernible fear convinces Cassidy that the woman does believe in ghosts. Pauline admits that she’s less skeptical than she let on because she’s seen things she can’t explain. At the train station, evidence of malfunctions on other trains shows that Thomas is getting stronger and more dangerous. Cassidy tells Pauline the truth about her gift, Jacob, and their current mission, but Pauline isn’t convinced. At Sylvaine’s apartment, they meet her daughter, Adele, who appears to be just a bit younger than Cassidy. However, Sylvaine is upset by the subject of Thomas’s death, refuses to talk about it, and sends them away.
