Summary

On June 10, 1978, Vi breaks the house's most sacred rule: she sneaks into the basement, the one place Gran has declared strictly off-limits. The basement is Gran's private laboratory, where she conducts experiments on mice and rats, performs dissections, and studies brain tissue under a microscope. Vi is terrified—the smells of formaldehyde and bleach, the caged animals with their glowing red eyes, and the memory of the fetal pig in a jar all unsettle her. But she has promised Iris she would find clues about Iris's past, and promises matter to Vi.

Eric and Iris serve as lookouts: Iris sits at the top of the stairs ready to flash the lights if Gran approaches, and Eric watches from the front door to stall Gran if she comes across the yard. Vi moves through the lab, noting the numbered cages, the surgical table, and the locked cabinet holding the killing jar and chloroform. She recalls a recent lesson where Gran taught her to euthanize a mouse that had failed an experiment—a memory that still haunts her.

On the workbench, Vi finds one of Gran's notebooks. Despite knowing it's forbidden, she opens it. The first page contains questions about memory, trauma, and whether memories exist on a cellular level. Flipping ahead, she reads a note: “L.C. not doing well lately. Sending her down to B West.” Then she finds the last entry, dated yesterday, titled “Mayflower Project Notes,” describing a patient “S” who shows tremendous progress, has no memory of her past or of B West, and is learning quickly. The entry ends mid-sentence: “Perhaps, one day, I’ll be able to show her off to the world, to truly—”

The lights flicker—the signal. Vi slams the notebook shut, replaces it, and races upstairs just as Gran enters with Eric. Gran is short-tempered, snaps at Eric about his Big White Rat story, and retreats to her study, locking the door.

Vi, Eric, and Iris follow her into the kitchen. Vi uses the wall phone to eavesdrop on Gran's call with Dr. Hutchins. Gran is furious about a new nurse, Patty, who has been asking questions about B West and even tried to go into the basement. Gran tells Dr. Hutchins she's told Patty that B West is just storage, but Patty heard patients talking about it. Dr. Hutchins promises to talk to Patty and ensure she stops asking.

After the call, Vi tells Eric and Iris they need to get into the Inn and talk to Patty. Eric worries about getting past “Miss Evil,” but Vi insists they have to.

Character Development

Vi: This chapter shows Vi's internal conflict between being “Gran's good girl” and her loyalty to Iris. She experiences a “strange rush” from breaking the rules, but also deep fear. Her promise to Iris drives her to defy Gran, revealing her growing independence and moral compass.
Iris: Though she doesn't speak much, Iris's role as lookout and her panicked look when Gran arrives show her investment in the plan and her trust in Vi.
Eric: He's the comic relief and the cautious one, worried about getting caught. His attempt to listen in on the phone call nearly exposes them, but he remains loyal to the plan.
Gran: Her secretiveness deepens. She's controlling, dismissive of Eric's story, and clearly hiding something significant about B West and the Mayflower Project. Her notebook entries suggest she's conducting experimental treatments on patients, possibly erasing memories.
Dr. Hutchins: He's complicit in Gran's secrets, willing to silence Patty to protect whatever is happening at B West.

Themes, Symbols, or Motifs

Secrecy and Conspiracy: The basement is a physical symbol of hidden knowledge. Gran's locked study, the forbidden notebook, and the phone call all reinforce the theme of family secrets and institutional cover-ups.
Memory and Identity: The notebook's opening questions—about what the body remembers and whether memories can be erased—directly tie to Iris's mysterious past and the Mayflower Project's goal of wiping memories.
Medical Ethics: Gran's experiments on animals, the killing jar, and her willingness to alter patients' minds raise ethical questions about the cost of scientific progress.
Rebellion Against Rules: Vi's decision to break Gran's rules marks a turning point. The basement, once a place of fear, becomes a site of discovery and defiance.
Surveillance and Eavesdropping: Vi's phone eavesdropping mirrors the children's constant watchfulness. The light signals and lookout system show how the children must operate in secret to uncover the truth.

Why This Chapter Matters

This chapter is a pivotal reveal. It confirms that Gran is running a secret project—the Mayflower Project—that involves erasing or altering memories, and it introduces B West as a location tied to that project. The mention of “L.C.” and “patient S” hints that Iris may be one of Gran's subjects, possibly the “S” who has no memory of her past. Vi's discovery and her decision to confront Patty set the stage for the next phase of the investigation, raising the stakes and deepening the mystery.

Study Questions and Answers

1. What does Vi find in Gran's notebook, and why is it significant?

Vi finds notes about a patient “L.C.” being sent to B West and a “Mayflower Project” entry about a patient “S” who shows no memory of her past or of B West. This is significant because it suggests Gran is conducting experimental memory-erasure treatments, and it directly connects to Iris's mysterious identity—Iris may be the patient “S.”

2. How does Vi's act of disobedience affect her character?

Vi experiences both fear and excitement when she breaks the rule. She feels like she's betraying Gran's trust, but her promise to Iris overrides her guilt. This moment marks her transition from a compliant granddaughter to someone willing to challenge authority for the sake of truth and loyalty.

3. What does the phone call reveal about the adults' secrets?

The call reveals that Gran and Dr. Hutchins are actively hiding the existence and purpose of B West. Patty's questions threaten to expose something, and Gran is willing to fire her to protect the secret. This shows that the adults are complicit in a larger conspiracy, and that the children's investigation is dangerous.
