Despite promising to use his position as Train Detective to help the Tail plan their revolution, Layton does take his position seriously and attempts to solve the murder. He is assisted by Till, and the two talk with numerous passengers aboard the train. Eventually, they begin to suspect the butchers, with Layton suggesting that [[Sean Wise|Sean]]'s missing limbs are being used in the kitchen as food; Till rejects this idea, however, branding it ridiculous. During their investigation, Till takes Layton to the Nightcar in a bid for him to better understand Nikki's job.

Later, they find the missing body parts behind a vent in the butcher's fridge; they surmise, however, that the butcher came second, given the torture Sean endured during his castration. He later realises that Sean was a Wilford informant and was tortured for the secrets he knew.<ref name="s1e02">''[[Prepare to Brace]]''</ref>

Layton and Till eventually realise that Kronole is a street-drug synthesised from the suspension drug used aboard Snowpiercer, and that this has caused [[Nikki Genêt]] to fall into Kronole withdrawal. Layton is able to eventually tie one of the janitors, [[Terence]], to Sean Wise's [[Kronole]] business, and finds out that Sean — along with another man — bought Kronole from him the night of his death. He later relays this information to Melanie and Roche.<ref name="s1e03">''[[Access Is Power]]''</ref>

Layton is furious when news of [[Nikki Genêt]]'s death reaches him. He questions why Melanie did not act on the description he had given her previously — Melanie remarks that she was waiting until the morning. Layton finally realises that the killer must be from First, given the schematics of the lockdown during Fight Night; Melanie agrees to allow Layton to question First.

Layton questions First, and [[LJ Folger]] reveals that her bodyguard, [[Erik]], did not return home that night. After numerous hours of questioning, it becomes clear that LJ is behind the murders and Erik is her puppet, doing as she pleases. She is arrested after attempting to stab Layton.

Following this, Melanie realises that Layton has figured out that Mr. Wilford is fiction, and the real leader of [[Snowpiercer]] is Melanie; he remarks that a myth is a powerful thing, but Melanie has him suspended in the drawers in an attempt to protect her identity.<ref name="s1e04">''[[Without Their Maker]]''</ref>
