The world's rarest fish has been stolen from the city aquarium. The police have followed the scent to a street with five identical looking houses that are next to each other. But they can't search all the houses at once, and if they pick the wrong one, the thief will know they're on his trail. As the city's best detective, it is up to you to solve the case. The police tells you what they know:

• Each house's interior walls are painted of a different color. (Red, Yellow, White, Blue, Green).
