The best mystery I read was the Adventure of the Blue Carbuncle. I liked the way Sir Arthur Conan Doyle composed the story and the way the ending got made. It really was hard trying to find out what went on with each clue.
"I walked into the house and heard an eerie tune that made my bones chill. I turned on the lights and saw my father sitting at the kitchen table.He was motionless. He had a grin that made him look like he had just won the lottery. My presence was of no concern to him, for he just sat there. I checked his pulse. He was dead."
