Chapter 87: Baby Unmasks a Killer’s History

!!! SPOILER WARNING !!!

This page contains complete plot details from Chapter 87 of 2 Sisters Murder Investigations. Read only if you have finished the chapter or don’t mind major reveals.

Summary

Baby watches Su Lim Marshall’s eyes and sees the woman mentally rifling through her own violent history. Marshall recalls each person who crossed her and died suspiciously: a South Korean ex-boyfriend who committed suicide after being framed for forgery, a landlord who plunged down the stairs after raising rents, and two former husbands—one lost at sea, the other gunned down in a drive-by. Baby and Jamie have already spent hours cutting through Marshall’s web of aliases, addresses, and accounts, so Baby knows Marshall is gauging how much has been uncovered. When Marshall moves toward a sleek cabinet, Baby immediately recognizes the decision to kill. Marshall doesn’t bother with a pretext, treating Baby as an inconvenience to erase.

Rather than reacting, Baby sits quietly and listens—a skill she has practiced while overhearing her housemates adjust to their new living situation in Manhattan Beach. Just as Marshall’s hand closes on a weapon in the cabinet drawer, the office door bursts open. Rhonda appears, straining to hold Mouse’s chain as the massive dog snarls and barks with hellish fury. Mouse seems to know exactly who poisoned him. Rhonda orders Marshall to release the weapon and raise her hands. The chapter ends in a frozen standoff.

Key Events

  • Baby watches Marshall mentally review her trail of suspicious deaths: an ex-boyfriend, a landlord, and two husbands.
  • Baby reflects on how she and Jamie dismantled Marshall’s fake identities, names, and accounts.
  • Marshall decides to kill Baby, showing physical “living rigor mortis” as she walks to a cabinet with a hidden gun.
  • Baby intentionally doesn’t move or engage, instead practicing quiet observation.
  • Rhonda and Mouse burst into the office, Mouse enraged and seemingly aware Marshall poisoned him.
  • Rhonda commands Marshall to let go of the weapon and put her hands up.

Character Development

  • Baby: Exercises restraint and insight, choosing to observe rather than panic. Her deliberate silence contrasts with her earlier impulsiveness and shows how recent danger has sharpened her instincts.
  • Su Lim Marshall: Exposed as a calculating serial killer who doesn’t bother to mask her intentions. Her past is a chain of lethal eliminations, and her coldness is compared to a machine.
  • Rhonda: Emerges as a fierce protector, physically anchoring herself against Mouse’s strength while issuing a direct threat.
  • Mouse: Displayed not just as a pet but as a creature with an almost supernatural sense of grievance toward the woman who hurt him.

Themes, Symbols, or Motifs

  • Listening vs. Talking: Baby notes she has spent the past days listening instead of speaking, a deliberate shift that allows her to survive this moment.
  • Disconnection and Automation: Marshall’s murderous impulse is described as “living rigor mortis” and compared to a Roomba’s detached, automatic movement, emphasizing her inhuman detachment.
  • Family as Shield: Rhonda and Mouse arrive as a unified force, representing the chosen family that repeatedly rescues the sisters from physical and emotional peril.
  • False Identities: The labyrinth of aliases and accounts symbolizes the layers of deception hiding a predator in plain sight.

Why This Chapter Matters

This chapter delivers the long-awaited face-off between Baby and the architect of the sisters’ nightmare. It crystallizes Marshall as a remorseless, almost mechanical killer while simultaneously cementing the bond among Baby, Rhonda, and Mouse. The tense, quiet buildup—ended by a door crashing open—shifts the power dynamics in a single second and sets the stage for the final confrontation or arrest.

Study Questions and Answers

  1. How does the chapter show the difference between Baby’s old and new approach to danger?
    Baby admits she once would have talked or reacted; now she deliberately stays silent and listens, a survival technique learned from observing her grieving and adjusting family members.

  2. What does the comparison of Marshall to a Roomba convey about her character?
    It suggests she kills with such routine detachment that her body performs the task automatically, without emotional or moral engagement, reinforcing her identity as a methodical predator.

  3. Why is Rhonda’s physical struggle with Mouse significant?
    It visually dramatizes the cost of protection. Rhonda must throw her entire 260-pound frame into holding Mouse back, showing that shielding loved ones from evil requires immense strength and sacrifice.
