Dixon]].

== Series background == The ''Undercover Brothers'' is about two teenage brother detectives, [[List of The Hardy Boys characters#Frank Hardy|Frank]] and [[List of The Hardy Boys characters#Joe Hardy|Joe Hardy]], who are the sons of world-famous [[Private investigator|PI]] [[List of The Hardy Boys characters#Frank Hardy|Fenton 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.<ref name=":0" /> 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]] style with Frank and Joe alternating chapters and often interrupting each other.<ref name=":0" /> * [[List of The Hardy Boys characters#Aunt Gertrude|The Hardy boys' aunt]]'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, [[List of The Hardy Boys characters#Callie Shaw|Callie Shaw]] and [[List of The Hardy Boys characters#Iola Morton|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 [[List of The Hardy Boys characters|Playback]].<ref name=Wanted>{{Cite book |title=Wanted |author=Dixon, Franklin W. |date=2006 |publisher=Aladdin Paperbacks |isbn=9781416912583 |location=New York |oclc=68464677 |url=https://archive.org/details/wantedhardyboysu00fran_0}}</ref>
