Wanting to examine the weapon more closely, Mortimer takes it with him before leaving the SUFOS offices, but, overcome with natural fatigue, returns it to Kaufman before booking into a hotel. During the night he is attacked by an intruder who is wearing the same glasses and using the same weapon as Macquarrie had. Mortimer fights back and the man falls out of the hotel room and is killed on hitting the ground. Mortimer then finds that his face is a mask covering a green, highly deformed, alien-like head. Warned by Mortimer, Kaufman has the body taken to SUFOS.
