With new information about Aaron Peel, Villanelle goes undercover as a New Yorker named Billie to befriend Aaron’s sister, Amber but there is conflict between Villanelle and Aaron.

In a desperate attempt to get closer to Villanelle, Eve puts out a hit on herself, hiring Villanelle to do the job.

Villanelle is ordered by Raymond to perform a clean assassination like the Ghost. She kills her target in a lift and delivers lipstick to Eve with the name “Love in an Elevator” to ensure that Eve knows who performed the assassination.

Eve meets her new team and deduces that the murderer is not Villanelle, but a new assassin for the Twelve whom she nicknames “the Ghost”.

While founding wounded Villanelle, Eve is called back to London to investigate a murder case believed to have been ordered by the Twelve. Villanelle has a rough time as she makes her way from a Paris hospital to London.

Eve investigates Anna, Villanelle’s former teacher, with whom she had a deep relationship before Villanelle killed her husband.

Eve and Carolyn track down Nadia to a Moscow prison, and are allowed to speak to her due to Carolyn’s camaraderie with two Russian Intelligence officers, one of whom is Konstantin.
