Nick and Honey Addams return home to find their baby-sitter, Jess Lake, murdered. She was tied to a bed and indeed often posed for bondage and fetish shots for photographer Marion Hammond. She also worked in a university lab with her boyfriend Gideon's father Dr. Massey, who is divorced from his unfeeling wife Stanza. Honey admits that Nick does not have an alibi but he seems to have no link to the next victim, Jess's house mate Silas, whose corpse is also arranged in the style of one of Marion's photos. Lewis finds himself tracking a killer who is a seemingly respectable citizen but who has a split personality rendering them an obsessive.
