Chapter 28 - Hostile Territory
Whilst playing as Abby, you'll come a China town-esque area whilst you're hunting down Owen.
During this scene there's a sprint jump you'll need to make in to a antiques dealer, whilst exploring all the shops in the area.
Go left when Abby gets to her feet and follow the path to a hole in the floor. Instead of jumping down, turn right and the artefact is on a counter in the right hand corner.
NOTE: Time delay on trophy pop, it didn't pop for me until I jumped down the hole in the floor.
