***The Hardy Boys: Undercover Brothers*** is a detective fiction series of books published by [Aladdin Paperbacks](/source/Aladdin_Paperbacks) (an [imprint](/source/Imprint_(trade_name)) of [Simon & Schuster](/source/Simon_%26_Schuster)), which replaced [The Hardy Boys](/source/The_Hardy_Boys) Digest paperbacks in early 2005.[1] All the books in the series have been written under the [pen name](/source/Pen_name) of [Franklin W. Dixon](/source/Franklin_W._Dixon).

## Series background

The *Undercover Brothers* is about two teenage brother detectives, [Frank](/source/List_of_The_Hardy_Boys_characters#Frank_Hardy) and [Joe Hardy](/source/List_of_The_Hardy_Boys_characters#Joe_Hardy), who are the sons of world-famous [PI](/source/Private_investigator) [Fenton Hardy](/source/List_of_The_Hardy_Boys_characters#Frank_Hardy). Although there are many similarities in this series to the previous *Hardy Boys* series, there are also many changes, for example:

- The Hardy boys are undercover agents for American Teens Against Crime (ATAC), a top-secret government organization, co-founded by their father, and are solving more realistic and violent crimes.[1] Since it is a top-secret organization, Frank and Joe often need to make up excuses to convince their mother and aunt to let them go to places.

- The books in this series are written in a [first-person narrative](/source/First-person_narrative) style with Frank and Joe alternating chapters and often interrupting each other.[1]

- [The Hardy boys' aunt](/source/List_of_The_Hardy_Boys_characters#Aunt_Gertrude)'s name is shortened from Gertrude to Trudy. It is revealed in *Hurricane Joe* why she shortened her name to Trudy. This version is much younger than the character in other Hardy Boys series.

- The Hardy boys' long-time girlfriends, [Callie Shaw](/source/List_of_The_Hardy_Boys_characters#Callie_Shaw) and [Iola Morton](/source/List_of_The_Hardy_Boys_characters#Iola_Morton), appear in the books, but only as platonic friends of the boys instead of love interests. Other friends from the original series are occasionally mentioned but never play important roles as they did in the past.

- The Hardys have a pet parrot named [Playback](/source/List_of_The_Hardy_Boys_characters).[2]
