Setting
The narrative unfolds in contemporary times on the Fitzgibbon farm. The Fitzgibbon residence acts as the backdrop for the habitats of nearby animals. These animal homes are depicted with vivid detail. Mrs. Frisby and her offspring, a family of mice, reside in a "slightly damaged cement block [that] . . . lay almost completely buried" in Mr. Fitzgibbon's field. The interior of their home consists of "bits of leaves, grass, cloth, cotton fluff, and other soft things Mrs. Frisby and her children had collected." The Frisbys inhabit this place during the winter since living in the woods becomes too difficult due to the lack of food. The farm offers Mrs. Frisby and her family shelter and leftover crops for sustenance, but it is fraught with danger. Mice are constantly aware that this is cat territory, and when Mr. Fitzgibbon starts plowing in the spring, "no animal caught in the garden that day is likely to escape alive, and all the winter homes, all the tunnels and holes and nests and cocoons, are torn up."
While Mrs. Frisby's abode seems like a realistic mouse dwelling, the escaped rats from NIMH have constructed an extraordinary world beneath the rosebush on the Fitzgibbon farm. The rats have set up a fully organized base in a cavern, utilizing electricity to operate lights, an elevator, air ducts, and a radio. They have a well-stocked library and convene in a large assembly hall to deliberate on the future of their society.
Literary Qualities
Some key literary elements of Mrs. Frisby and the Rats of NIMH include the portrayal of animals with human-like traits, intricate character development, layered narratives, the use of flashbacks to vividly depict past events, and settings that highlight themes, personalities, and conflicts. O'Brien crafts animals that are "humanized," meaning they think, feel, speak, and respond in ways similar to humans. The conflicts they face mirror human struggles. Mrs. Frisby emerges as a convincing character who conquers her fears, gaining a sense of independence. Attributes such as fear, bravery, insensitivity, and kindness are shown as aspects of a character's multifaceted personality.
By the entrance, observing her with dark, unwavering eyes, stood the largest
rat she had ever seen.
The author expertly intertwines the struggles of Mrs. Frisby and the rats, not
only through the storyline but also through the detailed exploration of
corresponding themes and conflicts. Nicodemus's recounting of their time at
NIMH spans eight chapters, yet it unfolds through action and dialogue, forming
a narrative within the main story. The use of flashbacks, rather than
straightforward monologue, effectively sustains action, suspense, and
engagement.
The settings are well-defined and often reflect elements of theme, conflict, or character. The depiction of Mrs. Frisby's home is realistic; she does not wear tiny clothes, nor does she have miniature versions of human furniture in her house. In contrast, the rat colony is described in more fantastical terms, highlighting their use of modern technology against Mrs. Frisby’s more natural or primitive surroundings.
The constant struggle and balance between life and death are suggested by Mr. Ages' home, which "had a bleak and almost ghostly look, for the blossoms and the green leaves were gone, and only the dry skeletons of the weeds stood, hung with stalks and seeds and pods that rattled in the wind." Yet, it is from these very seeds that Mr. Ages "made the draughts and powder that could sometimes save the sick from dying."
