The new girl at school has long blonde hair & big blue eyes, so naturally Damian is fascinated when she says that her grandparents' house is haunted. As the local specialist detective, he feels honour bound to solve the mystery! He agrees to spend a night in their bedroom, to see the ghostly white figures for himself
- & when the ghosts appear, they go into their nightly mime of one throttling the other. But this time Damian throws himself at them, & they turn out to be very solid humans wearing sheets!
