Sandra had always been fascinated by mysteries. She loved reading detective novels and watching crime shows on TV. But her obsession with finding hidden conspiracies and clues had always been dismissed by her sister, Carrie, as a silly quirk.

One day, Sandra received a frantic call from Carrie. She had been accused of murdering the man in the next apartment. Carrie swore she had never even been in that apartment before, but her DNA was found all over the place.

Everyone, including the police, believed that Carrie was guilty. But Sandra refused to believe it. She knew her sister was innocent and was determined to prove it.

Sandra started investigating the case on her own. She went to the crime scene and looked for any clues that might have been missed. As she was searching, she heard a strange noise coming from the apartment next door. It sounded like someone was trying to break in.

Sandra quickly called the police, and they arrived just in time to catch the intruder. It turned out that the intruder was the real killer, and he had planted Carrie’s DNA at the crime scene to frame her.

Thanks to Sandra’s quick thinking and determination, Carrie was cleared of all charges. From that day on, Carrie never laughed at Sandra’s obsession with mysteries again. She knew that her sister had a gift for solving them, and she was proud of her.
