Miss Perumal is Reynie’s tutor at the Stonetown Orphanage. Before he meets his friends in the Mysterious Benedict Society, Miss Perumal is the only person in Reynie’s life who genuinely cares about him. She assures him of his intelligence when he doubts it and helps him register to take Mr. Benedict’s tests. Though Miss Perumal is absent for much of the book, she remains one of the most important people in Reynie’s life. When he is away at Mr. Curtain’s Institute, he writes mental letters to Miss Perumal in an attempt to sort out his internal conflicts, and the thought of Miss Perumal helps him resist Mr. Curtain’s mind-controlling Whisperer. After the children defeat Mr. Curtain and return to Stonetown, Miss Perumal adopts Reynie, finally giving him the family he has always wanted.
