What do you do about the door when you enter? You look in the closets, under the bed, and in the bathroom. If a man is in there, you want to be able to run out, screaming for help. Therefore, you should leave the door open. But if you leave the door open while you are making a search, what is to prevent the Strangler from following you in and standing between you and your means of escape when you first see him? Do you enter the apartment, lock the door, and then start searching; or do you leave the door unlocked, or open, and make a hurried search?
