George - The Flower Shop, Bijou's Apartment | Paris - The Next Visit Broken Sword: TSC Guide

During a longer cutscene you will get in possession of Yarn. Your number one goal is now to leave the building guarded by Sergeant Moue.

Make the officer go away

Talk to Nico. Examine the Boxes on the right and take a small toy, Manneken Pis, out of them. Take the Flowers under the counter too. Talk to Fleur - and be aware that is a point in which the game often crashes. Open Options - Visual Settings - UI and change Modern to Classic. This should help.

It's a shame the game isn't more polished

Talk to Adam about CD Player and offer him a Coin. He'll leave, leaving the player on the counter. Click it.

This will help you escape the police

Press the Stop Button, then the Eject Button. Click the Compact Disc to take it. Now, remove the Battery Compartment and take out the bare Battery. There's a Stereo on the counter - use the Compact Disc on it. The Sergeant seems interested in the music. Put the battery in the toy and then fill the toy with whiskey. Use it on the Trolley left of the counter.

The trolley has wheels

Push the trolley - by clicking the Manneken in a Trolley. The officer will want to have a bathroom break, giving you a chance to escape ("Fountain of Youth" achievement). Head to Bijou's Apartment.

Time to get some information

Use the intercom and go upstairs. Talking to the woman, choose Hobbs and Provenance, but you'll also need to show her the Diamond Ring and Hobbs' Note. She will agree to help you. You will now be heading to London.
