Episode 512: The Broken Astrolabe ★★★★

The main story is about Kogoro being invited to interview the famous fortune teller, Reika Shijo, and Conan and Ran accompany him to her house. Unexpectedly, Reika is later found murdered in her room in a locked-room mystery. Conan investigates the several people involved in the house and finally solves the locked-room trick to find the killer. Ran only tells Conan about the crystal pendant the deceased gave her, but it's eventually revealed through the sleeping Kogoro... The place Conan hid after shooting Kogoro was quite obvious, but the overall plot was reasonable, so I give it four stars.
