Detective Conan Episode 487 «500+ Safe»

I need to structure the paper. Start with an introduction about Detective Conan and the Sherlock Holmes arc. Then, outline the plot of episode 487. Maybe the setup where the students are invited to a party at Professor Mori's place, where a murder occurs. Discuss the suspects: Holmes (Conan), Watson (Haibara), Moriarty (Gorō), and others. The case involves a murder where it seems impossible for any of them to have committed the crime, but Conan solves it with his deductions.
