What is the fine-grained topic of the following text: In Camelot, Merlin and Arthur have eloped (Merlin is in reality an ambitious and very well disguised woman), leaving the wizard's cave to her two apprentices and her sister, They start the Temporal Detective Agency, but without Arthur Camelot crime is boring so they use Merlin's Time Portal to move to the 21st century where the cases are more interesting and the toilet facilities so much better.
