Bonnet reaches Louis Carnot's residence in the evening. Leaving the bike on the side of the road she heads towards the gate (closeup). She pulls the doorbell on the right to summon the security guard. She fails to convince him to let her in. Nicole walks along the wall (to the left) and notices that there is a spot when it's a lot lower then in other points. (right click on it) - this gives her hope to reach the palace if she's not let in through the main entrance.
There's a phone booth nearby and she looks inside, just in case (zoom in) she finds there a large stone, holding a page in the phone book, a film case and a small stone (on the phone). After taking a closer look at the case she notices it's not empty - inside she finds a small hook with a sucker.
That's pretty much all she can find here, so she goes back to the gate and takes the rocky path down to the harbor. She finds two boats here - the one closer to the land is damaged (closeup) so Nicole decides that no one will mind if she picks up a rope and a large bucket from it. In the bucket she also finds a small screwdriver (right click on the bucket, then left click on it) and a small bottomless bucket. She also grabs the green board laying on the solid ground.
She then heads towards the second boat and examines it (zoom in). She attaches a rope to the boats end and places a board over the rope creating a makeshift gangplank allowing her to get onto the boat (zoom out and click on the boat) while on the boat she lifts the anchor (on her own) and heads back to the back of the boat (zoom in) and picks up the board and the rope - she will make use of them later on. Before leaving she uses the film container to grab some sea water. She goes back to the front of Carnot's residence, connects the rope to the anchor crating a climbing set. She cannot however get onto the wall yet, as the guard is patrolling the area - she needs a distraction.
To create it Nicole approaches the gate (close up) and places the large bucket, small bucket and the board just beneath the bell. She uses this construction to climb up and reach the cornice above the bell (close up) placing there the large rock and the container of sea water into which she throws an aspirin. Then, she runs left to the wall.
She waits for the aspirin to drop the rock and trigger the doorbell and then climbs over the lowest part of the wall (!) using the rope and anchor. She then heads right. (This task is timed, however there's quite a lot of time to finish it. Throwing the rope and climbing up shouldn't take too long, as the guard may be heading back any moment. If you fail to do this in the given time you can try again, but each time you have to run down to the harbor to fill the container up.
