Show the photo to people around the island. When you ask at Downtown, the mimes act out "playing music", indicating they have seen him in the All That Jazz Cafe.
once you figure it out he runs away and you have to chase him on a scooter then he drives away on a motor boat
The mimes are street performers Downtown, in front of the Clown Store. There only function is to tell you where the thief has gone once the museum has been robbed. If you show the thief's picture to anyone Downtown, you are dragged over to the mimes, who act out "playing music". This indicates that the thief is at the All That Jazz cafe.
Once you get the time card from the security guard (he's at the Clown Store) you can check the surveillance video for the likely time, and get a photo of the thief.
The lady Chief Inspector is nowhere to be found once you leave the Security Room with the photo of the art thief.
Once you have found and chased the thief, the investigator (Chief Inspector) is nowhere to be found. Once you have the key from the curator, you can open the Inspector's house in the Countryside to locate the painting.
Once released, the island is available by using the island map.
Directly from the map (once it opens).
Once you have recovered the timecard from the security guard at the Clown Store, you can get the photo of the thief and talk to the Inspector at the museum's Security Room. She is there until the scooter chase with the thief (shady guy), and then she is gone.
Once you have passed the Forgery Training, you will receive a key to the Supply Room. You have to use it to get the Dragon Face picture piece in the room, so that you can complete the picture and enter the museum at night.

in the cave you get a piece of the picture, and once you have the whole picture you copy the picture on the lock in this big dome above your head, and it will get you into a secret door that leads you to the supply closet so you can sneak into the museum at night to "protect" the painting
The Black Widow has an underground lair. You can get to it once you receive the house key for the Country Side. After you chase the thief (shady guy) on the scooters, go to the museum and get the package there.
