Rob finds a book that seemed to come from nowhere, he opens it and it seems to have instructions on how to effectively strangle someone, the book puts him in a trance and makes him put in practice what he learns. Rob learns how to choke someone to death with a sleeperhold, he practices with a pillow, but he hears that one of his roommates arrived, Ed came from a run and he finishes some exercises before sitting down to meditate. Rob takes the chance and places himself behind him, Ed is concentrated and doesn't notice anything until it is too late, Rob wraps his arm like a python around Ed's slender neck, he tries to break free, but Rob is strong, too strong; Ed chokes and fights, but Rob keeps closing his hold, constricting Ed's neck by the second until he exhales his last breath. Rob has killed all of his friends, he snaps out of the trance and he is terrified for what he has done, not able to explain what happened, the book disappears...seeking a new student...
