there used to be a big office at baker street with all the lost property. they had all sorts of stuff in there, medical students in euston used to steal body parts and leave them as pranks. Theres probably a few films on it. The upside to this story is ive been reminded of the existence of lost property rooms. Perhaps the Tory central office has been looking for a failed experiment called susan hall in the wrong places and shes been running about on the tube all along. By the time they arrive shes run away because of all the black people in her head trying to nick her oyster card
