I assumed MS was Muriel Spark, but it's Mary Shelley. F is Frankenstein and O is Orkney, where the good doctor F attempted to create a mate for his creature.
Mary Shelley apparently spent some time in Dundee. Wonder where she got the idea for hulking misshapen creatures arisen from the dead.
I'll now contemplate devising a new question, unless anyone wants to chip in in the meantime.
