Mrs Croker



Mrs Croker is the ghost hunter who, along with her lackey Clarence DeSniff, tracks down random ghosts and tries to capture them. She is able to track ghost by a powerful sense of smell and uses her "ghost immobilising vapour" (GIV) to immobilise the ghost and then traps them inside small glass bottles.

She has a large collection of bottled ghost, hidden in the back room of her sweet shop cover job, but as the series goes on she becomes rather obsessed with William Povey, the shoeshine boy.
