Dillweed's Revenge — Florence Parry Heide

Dillweed's parents go on adventures and leave him behind with Umblud the butler and Perfidia the maid, who treat him like their slave. Neither Umblud or Perfidia or the parents appreciate Dillweed's cherished pet, a creature named Skorped. When they threaten Skorped's life and well-being, Dillweed opens his black box and casts the runes, which releases smoky monsters, who do the dirty deeds. And then it's Dillweed's turn to go on adventures.

Filled with nasty characters, beautiful details, and subtle humor, this stylish book follows in the tradition of the deliciously dark work of Edward Gorey, so Dillweed's happy ending undoubtedly means the end for someone else.
