Other mistake: Amazing that nobody sees the hooker's dangling body before that boat tour which looks like it's around nine, plenty of time for somebody else to notice her.
Vermeer: What do you think she meant when she said a huge black monster with giant claws?
Eric Visser: I don't know, but I hope your mother-in-law has an alibi.
Vermeer: UGH.
