The lodger has left.

I stuck a cheap camera in the computer room and connected it to the VCR in
my bedroom. After recording her in the computer room going through all the
desk drawers and paper files I then moved the camera to my bedroom and
recorded her looking through all drawers, cupboards and wardrobes.

I gave her 3 hours notice to leave. The bond I have will cover cost of the
change of door locks.
