Bentley: Sly! Come in! Sly! Do you read me?
Sly: Yeah. I read you. Loud and... very loud.
― At the start of the job[src]
The mission took place one night in Paris, France. Sly Cooper snuck across some rooftops to get into position on the roof of Police Headquarters. His task was to break into the station and steal a secret police file from Inspector Carmelita Fox's office, with the help of his friends Bentley and Murray. The file was very important to Sly, as it contained information on himself and a villainous organization known as the Fiendish Five.
Once Sly was in position, Bentley appeared on his binocucom, expressing his nervousness about breaking into the station, but Sly soothed him with the reminder that he is the thief here. With the station's security system fully scoped, Bentley directed Sly to an air vent that would lead him inside. Shortly before the briefing was over, Murray also appeared on the line to remind Sly that he was behind the wheel and would be prepared to take off when Sly was ready. As Sly approached the small water tower on the roof, he noticed some interesting blue sparkles along the ledge. Having already read about them, Bentley explained that master racoon thieves are able to sense thieving opportunities, which manifest themselves as blue stealth auras, sparkles that would allow Sly to perform sneaky moves, such as sneaking around ledges. Upon reaching the vent, he busted through it and made his way inside.
Once in, Sly came across a vertical shaft littered with yellow criss-crossed lasers. After carefully jumping down the shaft and disabling the siren, he entered the hallways. He had to search for a red door, as Carmelita's office was supposedly located behind it. The door, however, may have been super-reinforced from the inside, therefore Sly had to make his way around to an open window by once again sneaking along a ledge. Once inside, he approached the vault, which contained the important file he was looking for all these years. After cracking the vault and taking the file, he left behind a calling card, and Murray informed him that they were waiting in the getaway van in the parking lot.
As Sly prepared to make his way down through the fire escape, he was caught red-handed by Carmelita, who leaped onto a nearby rooftop. Sly took this opportunity to reminiscence on their previous encounter in Bombay, where Sly stole the Fire Stone of India and was going to give it to her as a present. He then commented on how her shock pistol brought out the color of her eyes, but Carmelita warned him how dangerous her weapon was and suggested he surrender or end up paralyzed. Once the bantering between the two ended, Sly proceeded down the fire escape, with Carmelita firing at him and destroying the entire structure in the process. Sly then rushed through the parking lot to reach the Cooper Van. Once Sly made it inside, the gang drove off, leaving Carmelita shouting out in anger.
- The soundtrack for this level is also used in the hideout and "A Grave Undertaking," but in the PS3 remaster, "A Grave Undertaking" has new music. Its music was ultimately removed in the PS Vita remaster.
- There is a glitch in this level that allows players to free-roam throughout Paris (see here for more details).
- In the remaster, the music has been altered so that it plays the original version throughout the entire mission, instead of the new theme that plays after Sly sneaks past the water tower.
- In the remaster, Carmelita's line "Criminal!" does not sync properly. It is heard right when Sly jumps out the window, and when she appears and shouts out the line, no voice is heard.
