Question:
Can you answer this riddle?
A man was found dead in his study. He was slumped over his desk and a gun was in his hand. There was a cassette recorder on his desk. When the police entered the room and pressed the play button on the tape recorder they heard: "I can't go on. I have nothing to live for." Then there was the sound of a gunshot. How did the detective immediately know that the man had been murdered and it wasn't a suicide?
Also, the detective is not the murderer.
Answers:
because if he'd actually shot himself he wouldn't have been able to press stop so the detective would have had to rewind the tape, but since he just pressed play that means someone else was there.
