who wrote the letter in tell me lies

In Tell Me Lies (the Hulu series), Lucy is the one who actually writes the anonymous letter to the dean about Drew, but later Stephen tells Wrigley that he wrote it and takes the blame.

What the letter is

• The letter is an anonymous note sent to the Baird College administration, urging them to look into Drew’s involvement in the accident that killed Macy.

• It becomes a major catalyst for drama in the friend group and for Drew’s worsening anxiety and eventual expulsion.

Who really wrote it

• Lucy writes the letter after Stephen convinces her that Drew is responsible for Macy’s death, and she believes she is “protecting” Stephen by shifting attention away from him.

• She sends it anonymously, so most characters initially do not know she is behind it.

Why Stephen says he wrote it

• After Drew dies and Lucy is crushed by guilt, Stephen steps in and tells Wrigley that he wrote the letter, effectively taking the fall for Lucy.

• Cast and creator commentary frame this as a rare, partially selfless move for Stephen, but still mixed with his usual need for control and leverage over Lucy.

How fans talk about it online

• Forum and Reddit discussions often focus on Lucy’s motives, debating whether she truly did it to protect Stephen or out of guilt and anger over Macy’s death.

• Many viewers see the letter as the key symbol of Lucy and Stephen’s toxic dynamic: her secrecy and guilt, and his willingness to manipulate the situation even when he “protects” her.

TL;DR: Lucy writes the letter; Stephen later claims he wrote it and takes the blame.
