Note from Timsh is a written note found in The Knife of Dunwall.
Scott, do we really need that alarm device in my office? It's ugly, the colors clash, and the cable is marking up the woodwork. I am positively certain that the way it's been attached to the floor will cost a few thousand in coin to mend.
It can be found in a small room off Timsh's office, on a table beside the dumbwaiter during the mission Eminent Domain.
