As a profiler, you've just been recruited to create the psychological profile of a serial killer named Jack. This monster has cold-bloodedly murdered his own family and over a hundred people without distinction of gender or age.

To handle this delicate case, you've been granted psychological support in the form of Adam, a psychiatrist, who will accompany you during each of your sessions with Jack.

"Well, that's rather fascinating," Adam declares just after Jack vividly describes, in a disturbing level of detail, how he kept the same corpse in his apartment for over months. You're unsure about Adam's sidelong glance and the smile he gives you.
