This is a gallery of images for the episode: The Coded Map of the City Case.
Genta finds a piece of paper with weird symbols on it, and the word "Oro". The group (all except for Conan) think it could be a treasure map.
Unaware to Conan and friends there are three men searching for that piece of paper, but instead of claiming it, the men lurk and see what the kids will discover.
The group look at the first symbol on the map, it looks like the tower so they go to check it out.
Conan thinks the symbols on the map could relate to objects in real life, like an umbrella. The Detective Boys realise that all these symbols can be found at a clothing store.
The Detective Boys don't find any clues at any clothing stores. Conan asks if they could stop off at the book store where he finds a clue. The word "Oro" written on the map is Italian for gold. So Conan was wrong, it could be a treasure map after all!
Ayumi thinks that each of the symbols represents a sign near to the tower and if they follow the signs it should lead them straight to the treasure!
