Pale Lighthouse

Police officer “Warden” is dispatched to a remote island to find the whereabouts of a colleague who went missing.
While interviewing the island villagers, he learns about the village outsider, “Skoll.”

Vile, completely inconsiderate of others, and with an attitude that seems to look down on everyone but himself.
Yet somehow, he can’t hide the clumsy signs that he knows something. Because of that, Warden keeps seeking Skoll out.

Then, in Skoll’s house, Warden discovers traces suggesting that his colleague may have been murdered...

“You said you wanted to know how you’re different from Balt.
Sleep with me once, and I’ll tell you everything.”

How much of Skoll’s words should Warden believe?
