Riddle: Zane is a big boss in a hugely successful company. Every week, however, he finds out that one of his worst employees has been stealing his documents. After a whole year of stolen documents, Zane rounds up his three worst employees– Kelly, Raymond, and Natalia– and questions them. Kelly says, "Raymond has been stealing your documents!". Raymond says, "I haven't been stealing your documents!". Natalia says, "I haven't been stealing your documents, either!". Only one of the employees is telling the truth. Who has been stealing the documents, and which employee is telling the truth?
Answer: Natalia has been stealing the documents. Raymond is telling the truth. If Kelly was the one stealing the documents, then she would be lying, and Raymond would be telling the truth. But then, Natalia would also be telling the truth, which goes against the condition that only one employee is telling the truth. If Raymond was the one stealing the documents, then he would be lying, Kelly would be telling the truth, and Natalia would also be telling the truth. This also contradicts that only one employee is honest. If Natalia was the one stealing the documents, then she is lying. But then, who is telling the truth? It's not Kelly, because if it was so, both she and Natalia would be telling the truth, and Raymond would be lying, which doesn't meet the requirements. Therefore, Raymond is telling the truth, Kelly and Natalia are both lying, and Natalia is the one stealing the documents.
