Rennes' Pawnshop
From Tomb Raider Wiki
Daniel Rennes's place of business consists of several rooms in Cours la Seine in the Parisian Ghetto.
Summary
On previous visits Lara only saw the booth at the entrance, but having visited once Rennes is dead, sees the rooms behind as well. Behind the booth are several rooms - one large one where most of Rennes' belongs are kept, and a strongroom where he keeps weaponry and important documents. He also has access to the cellars below, and a pipe leading to the canal beyond.
