One Remained Seated

Maria Black, M.A., Principal of Roseway College for Young Ladies, is faced with murder in the cinema when a stranger seated in Number 11 on Row A is found to be dead. Assuming her role of detective, she becomes Black Maria - the crime solutionist. Working with Inspector Morgan, the local police chief, they go behind the scenes of a cinema, into the homes of those workers who'd maintained the entertainment industry- and into the recesses of a killer's mind.
