One character finds the secret diary of another character (almost always female), that contains all their darkest secrets and proceeds to read it and/or pass it around their friends, etc. Naturally, the character who owns the diary is furious when they discover this invasion of their privacy.

See also Diary.

Examples of Secret Diary include:


Advertising[edit | hide | hide all]

  • A commercial for AT&T U-Verse has the family seated around the dinner table. The son is reading the daughter's diary, which the parents have also read. The daughter is quite pleased. (The theme of the commercial is that having U-Verse makes everybody happy.)


Anime & Manga[edit | hide]

  • Slightly different set-up in Patlabor: Lt. Clancy is preparing a report on the rest of the team before leaving the force, and the others sneak into her apartment to read it.
  • Shiki Tohno finds Makihisa Tohno's hidden diary, in which it is revealed that the Tohno blood line contains demonic blood, that Akiha is one of those who has demonic traits, that Makihisa himself had a split personality, that Kohaku and Hisui are adopted synchronizers who can calm the demon blood by exchanging bodily fluids and that there was indeed a third child with the same name as Shiki that was adopted after Makihisa wiped his clan out.
  • The manga Wandering Son has a shared secret diary between the eleven-year-old main characters Shuichi and Yoshino, in which they write to another about their various Crossdresser experiences. When a boy gets ahold of the diary and passes it around, both kids in general and Shuichi in particular are ostracized. They start a new one not too long after.
  • In the ending to the anime version of Tona Gura, a pivotal diary that Hatsune gives Kazuki is Kazuki's own forgotten childhood diary which reveals that Yuuji's always been playful; teen hormones now make that playfulness obnoxious and immature, rather than cute. She also sees in it that she herself used to be a great deal more playful, but that she has also not outgrown her childish tendency to want complete control over how things are, especially with Yuuji. This marks a huge turning point.


Comics[edit | hide]

  • One wonders why Paige Fox of FoxTrot even bothers trying to keep a diary when Peter and Jason constantly read it openly. Jason has go so far as to post excerpts from her diary online and has even written in it (apparently on multiple occasions) a confession to really being an ugly alien being.
  • One Archie Comics story had Betty losing one of her diaries (to be more exact, the one she wrote about her moments with Archie in) and was worried that Veronica would get her hands on it. To make matters worse, Veronica overheard her and offered $100 to anyone who turned it in to her. Fortunately for Betty, Mr. Svenson returned it to her before anyone else could find it.


Fan Fiction[edit | hide]

Literature[edit | hide]

  • The disruption in Harriet the Spy.
  • William Sleator's Others See Us uses two stolen diaries as the MacGuffin, with the the inversion that the thief didn't steal them to read them, because she's telepathic and knows the contents already.
  • In Harry Potter and The Chamber of Secrets, Draco Malfoy plans to do this when he finds Tom Riddle's diary among Harry's possessions and mistakenly thinks it's Harry's diary.
    • According to Word of God, the way Riddle's diary uses Ginny is a serious Deconstruction of this trope, foregoing others reading the diary and instead making the diary itself a malevolent entity. J. K. Rowling finds diaries to be "really, really frightening" due to her sister confiding her innermost thoughts to a diary only to worry about people reading.
  • The book Click Here to Find Out How I Survived Seventh Grade is somewhat centered around this trope.
  • Subverted in the Liavek story "Paint the Meadows With Delight", where the main character steals her sister's diary in hopes of figuring out why she's been acting so strangely, and, since she can't read the language it's in, tries to get an older relative to translate it for her. It says much about the family involved that Jehane did't realise what she had done was objectionable until she got called out on it.


Live Action TV[edit | hide]

  • It is almost guaranteed that a Teen Drama series will have an episode centered around this at some point.
  • In House, House steals his ex-common law wife's psychiatrist's notes (mostly about how her relationship with her husband sucks and she has the hots for House again) and recites them to Wilson a few days later.
  • Red Dwarf: Rimmer walks in and finds Dave "waits for the film to come out" Lister reading. When he asks what the book is, Lister flat-out states that it's Rimmer's diary, then repeats some choice excerpts. Then:

Rimmer: I don't believe it! You've been reading it out to the Cat?!
Cat: Only the best bits!

    • Mild subversion here is that Rimmer isn't really surprised Lister's reading his diary: he's upset he's doing it publicly.

Lister: So you've read my diary.
Rimmer: Yes, but at least I have the common decency to do it sneakily behind your back.

  • Titus: Teenage Christopher comes home to find his father reading his diary to his poker buddies.
  • One scene in Spaced shows Tim reading Daisy's diary: "Ha, ha, ha, thrush!"
