There’s a monster under my bed...
Greta is a weird kid. The other girls don’t like her, her Dad left, and her Mum won’t get off the computer. When she starts seeing things that aren’t there she has to make a choice - is she going to let all this ride or get brave and wreak some Greek classical carnage?
Casting note: The Doctor could be female, also a chorus of several girls plus an unspecified number of puppeteers is required.
