The Dinner Party

You are the killer. You do not like that random people are partying around this mansion like its nothing. Even though you do not own this house, you are deeply involved with it. No one ever has known about the dark working history of the Arringtons', but you have been in the company from the beginning. One week ago, there was a breech in the company's file cabinet. The suspected thief is one of the people invited, but you do not know who. In your eyes, the only way to make sure the thief doesn't get out unscathed is to make sure no one leaves the party, no matter what it. You must not let anyone leave. What is your next move?
