Chapters 15-19Chapter Summaries & Analyses

Chapter 15 Summary: “Ellery—Sunday, September 29”

On Sunday morning, Ellery and Ezra are looking at Vance’s pictures in Sadie’s yearbook. They ask Nana about him, and she says she knew he wouldn’t last; she also says that Sarah didn’t go to homecoming before remarking that Officer Rodriguez is outside.


He comes inside, glad to see Ellery, and tells them that Brooke Bennett didn’t make it home the night before. Nana becomes upset that another girl is missing. Ellery is torn but knows what she has to do: Tell them that Malcolm is the last person who saw Brooke.

Chapter 16 Summary: “Malcolm—Sunday, September 29”

Malcolm wakes up to see Officer McNulty questioning Katrin about Brooke’s disappearance. Katrin says she texted with Brooke the night before, but that was all. Malcolm realizes with horror that he is about to repeat the same conversation that Declan had with McNulty about Lacey’s disappearance. 

Chapter 17 Summary: “Ellery—Sunday, September 29”

Ellery and Officer Rodriguez move into the kitchen, and Ellery recalls everything she can about the previous night. She repeats as much of the conversation as she remembers and mentions of the paperclip. When she comes to Malcolm giving Brooke a ride home, she makes a point to say that the ride wasn’t planned; this information piques Officer Rodriguez’s interest until she reiterates that it was pure chance that Brooke needed a ride home from Malcolm. Officer Rodriguez heads back to the station, saying that it will hopefully all turn out fine; given Echo Ridge’s history, no one believes him.

Chapter 18 Summary: “Malcolm—Sunday, September 29”

Malcolm is still being questioned by Officer McNulty as a witness, though he knows he is being treated like a suspect. When McNulty asks Malcolm if anything was unusual about Brooke, Malcolm looks at Katrin and says he doesn’t really know Brooke well enough to say. Katrin blurts out that Brooke thought Malcolm was cute and that the other night she stayed over and slipped out of Katrin’s room for a while; Katrin assumed she was going to see Malcolm. Malcolm denies this, wondering why Katrin would say it in the first place.


McNulty presses Malcolm to tell him everything he can about Brooke, and Malcolm brings up seeing her with Vance. McNulty says Vance was in the “drunk tank” the night before, but he will check up on it. He then asks if there’s anything else; Malcolm knows McNulty would want to know that Declan is in town but decides not to tell him. 

Chapter 19 Summary: “Ellery—Sunday, September 29”

Ellery is restless and pacing through the house, thinking of a story her Nana told her about Sadie breaking a figurine when she was 10. Sarah took the blame at the time, and Nana admitted that she was always harder on Sadie, a comment that causes Ellery to realize that Nana is also upset over Sadie’s current situation as “another cracked girl, broken and pieced clumsily back together” (159).


Malcolm texts and asks if he can come over, and Ellery agrees. While he’s on his way, she talks to Ezra about everything, and her true-crime brain can’t help but think of the possibility of Malcolm as a murderer. Ezra tries to be a voice of reason, but Ellery is still anxious over everything.


Malcolm arrives, and he asserts that he had nothing to do with Brooke’s disappearance. He also tells them about Katrin spreading rumors about a possible romantic involvement between him and Brooke, which he wants them to know about. When Ellery sees how scared and sad he is, she decides to believe him.

Chapters 15-19 Analysis

These chapters are driven almost entirely by plot, with the mirrored action of Ellery and Malcolm being questioned by the police over Brooke’s disappearance. Both of them are concerned with history repeating itself; for Ellery, that means being confronted with another victim, and for Malcolm, it means facing the fact that he’s a suspect just like his brother was. In some ways, they’re on opposite sides of the narrative they know, so it’s significant that Ellery chooses to trust Malcolm.


They both have reasons to be suspicious of the police during their interrogations. Ellery doesn’t trust Officer Rodriguez due to her belief in his incompetence, and Nana’s insistence that Sarah’s disappearance and Lacey’s murder were never solved reinforces this belief. Meanwhile, Officer McNulty has personal reason to dislike Declan and Malcolm, and Malcolm knows all too well what it’s like to be a murder suspect. This distrust proves to be unfounded, particularly for Rodriguez, but it explains why Malcolm and Ellery feel they need to take the case into their own hands.
