Miss Lupescu

Miss Lupescu first appears when Silas has to leave the graveyard for a while. She's the person Silas found to be Bod's guardian while he's away. At first Bod dislikes her, as to him, she seems like a poor substitute for Silas. She gives Bod lessons, but they're all boring. She's strict and says he must pay attention. And she makes Bod eat food he finds disgusting, such as " dumplings swimming in lard".

Despite Bod's initial dislike for her, she was actually helping him. Miss Lupescu was not only feeding Bod’s with home-cooked, high-nutrition food, she was also teaching him discipline and practical knowledge. She told him about all the supernatural beings in the world, including ghouls and Hounds of God. She also taught him ways to call for help in every language in the world. One language, Night-Gaunt, helped Bod escape Hell and the ghouls that wanted to turn him into a ghoul in Chapter [?]. Once Bod realized that Miss Lupescu's lessons were useful in his life, he became an enthusiastic student, drinking up all the knowledge she put before him. Bod and Miss Lupescu became friends, and she even took him to a football game. She saved him in Hell, because she was a Hound of God, and helped him escape and come home to the graveyard.

After Bod finally realizes that she and her big grey dog are the same, she writes him a note of explanation:

Those that men call Werewolves or Lycanthropes call themselves The Hounds of God, as they claim their transformation is a gift from their creator, and they repay the gift with their tenacity, for they will pursue an evildoer to the very gates of Hell.

This shows Miss Lupescu is religious, and she believes in God. Second, she suggests that all werewolves are Hounds of God. Unlike other works that feature werewolves, the werewolves in  The Graveyard Book  aren't portrayed as evil.

Like Silas, Miss Lupescu is a member of the Honor Guard and she dies battling the Jacks. She seems to be an important part of the fulfillment of the prophecy that if Bod reached adulthood, all the Jacks would be destroyed. She also was an important friend to Bod and many others.

She is likely of Romanian origin, as can be guessed by her name, formed of the Romanian "Lup"(wolf) and "-escu" (common family name suffix in Romania, eq. of French "-esqo"), as well as her outdated teaching practices that hearken to the Soivet era such as continuously asserting her authority through the raising of one's voice, assuming a higher standing than the pupil, the constant threat of physical punishment not for misbehavior but rather disobedience, and orders barked with no explanation. The cuisine that she cooks also resembles some Romanian cuisine, which came as a result of the traditional animal products and fresh vegetable rich Romanian diet meeting with Soviet Era food shortages and degenerating into an animal-fat and carbohydrate rich menu.
