How Did He Get In
Riddle: You sit at a chair when you hear gunshots. You look outside and hear a scream. No windows are open, no doors or open, and there are no people outside. The doors are locked and when you look inside a house you see blood, a dead man and a gun. How did the murderer escape and how did he get in?
Answer: It said the Windows and doors are locked. The riddle did not say anything about a broken window. You looked inside, but now did you know it was that house, because it had a broken window.
