Although you can Dodge the lasers by hiding behind statues, the video systems record anyplace that has light. This can come in handy later.
When entering the museum at night, you slip past the security office and then avoid the lasers in the statue room. When you reach the painting, jump onto it. This may not seem wise, since you immediately get caught...but it is the next step in the quest.
The Statue Room is the first room off the Gallery next to the Testing Room. Go right to enter the statue room, then left to reach the Security Room and the Storage Closet.
The statues are in a room between the gallery and the security room. Once you get the job and take the Forgery Training, you can walk through the Statue Room to reach the Supply Closet, to which you have been given a key.
They are the first persons you encounter when you reach Downtown. They are in front of the Clown Store, so you can't miss them.
Well, When you reach the farther game there will be a man who gives you a secret code for a secret exit.
The female "security guard" stays in the Security Room at the museum. The female guard who works for the Black Widow is on the third level of the lair, and walks back and forth to the left. When you climb past the first guard, jump up behind and carefully follow her until you reach the chair. Jump in the chair and bounce to the left.
If you mean on Counterfeit Island, the inspector's house is all the way to the left. Keep going left until you reach a large house.
There is a domed arch with a light bulb hanging down. Climb the cord to reach the piece near the ceiling.
You only use the Black Widow key card at the end of the island, to open the sliding doors in her secret hiding place.
Turning on the lights is not part of the museum "break in". Open the Dragon Face lock, slip past the Security Room, and avoid the lasers in the Statue Room. Once you reach the main gallery, the only place you can go is to The Scream painting, and that can only lead to one thing.
You use it much later in the game to reach the Black Widow's treasure lair. When you find it, put it aside and go back to the museum, where you have a package.
First, you unlock the supply closet. Don't pass the security office until the lady walked away. When she does, run past and into the statue room. When the lasers pass, hide behind a staue. Keep repeating until you reach the main room. Click on the Scream. Answer the questions correctly in the morning.
