Pip repeatedly tries calling Maria Karras, the mother of the convicted DT Killer. When the two finally connect, Maria says she left a message on Pip’s podcast website in April. Pip pretends that this is her follow-up call. Maria gives her details, suggesting that her son Billy couldn’t be the killer. She offers to send Pip a transcript of his interrogation.

Pip learns that Billy worked for the Green Scene landscaping company, to which other victims were connected. The company is owned by Jason Bell, the father of Pip’s original cold case victim—Andie Bell. Though Pip is unwilling to believe it, Billy may not be the real DT Killer, which means that the murderer is at large and after Pip.

The following day, jittery and sleepless, Pip pays a call at Jason’s house. He answers the door but won’t let her in. She asks about the security alarm that went off at his landscaping business on the night the fifth victim was killed. This was the same night that his daughter Andie died. He refuses to talk about the case anymore and accuses Pip of interfering in people’s lives.

Ravi arrives later for a visit, and Pip tells him about the numerous phone calls she’s now getting from a blocked number.
