Pokémon FireRed and LeafGreen/Rocket Hideout

Your sleuthing has landed you in the middle of a huge Team Rocket operation headed by a sinister figure known as Giovanni. The man in the slick suit at the rear of the Game Corner is actually guarding the entrance to a secret, underground lair. Giovanni has a prototype Silph Scope that can identify the ghosts back at Pokémon Tower. Don't let him escape!
