Gertrude "Trudy" Hardy is the unmarried older sister of Fenton Hardy, she lives with her brother and his family in the town of Bayport. She was given the nickname "Aunt Trudy" by Frank and Joe in the Undercover Brothers books and this tradition has continued into the Graphic Novels (which were based on the Undercover Brothers continuity) and into the Secret Files books.


She is a sharp tongued woman who isn’t afraid to voice her mind, never worrying how it will sound to others. She seems rather severe to strangers, but those who know her know that her peppery manner conceals a great depth of affection.[1]

Gertrude is very brave and will not back down to anyone; on more than one occasion she has managed to capture criminals that have sneaked into the Hardys' house.


A skilled cook, it seems Gertrude always has a freshly baked pie or a new batch of cookies for her nephews and their friends.

Like Fenton, Gertrude is gifted when it comes to detective work, and in the past she has helped him out with some mysteries.

Physical description

Gertrude is a 65 year old[2], tall, slim woman with long black hair[3]. She wears steel-rimmed bifocals and dentures.

In the Graphic Novels

She is tall and slim with blue eyes and short blond hair.


Gertrude Hardy was born to unknown parents on August 25th[4], presumably somewhere in New York state. Gertrude was popular in school.

At one time Gertrude was engaged, but before she was married her fiancé was killed[5].

She moved in with her brothers’ family shortly after Frank and Joe solved their first mystery, and has lived with them ever since.

Gertrude is descended from both Admiral Hardy and Great-Grandfather Hardy (although it is unclear whether they are one and the same person, or two separate people). During her adult life she was in possession of letters that Admiral Hardy had written in 1812, as well aa an oil-painting of Great-Grandfather Hardy that her brother, Fenton, remembered being above the piano in their childhood home. Both the letters and the painting were stolen from Gertrude when a criminal gang intercepted a parcel containing the items that were being sent by a friend who had been holding onto the box for Gertrude for a few years. With the help of her nephews, Gertrude later recovered both the letters and the portrait. [6]
