A series about Olivia Simon, a teenage girl who gets roped into a murder case after following her detective brother to the crime scene. With the help of her friends, Justin, Mae, and Chuck, she must find the killer before someone else ends up dead.
This story provides examples of the following tropes:
In the fourth book, Olivia and Chuck find a rhino 'tied to a parking meter', and bring it to his office for him to punch, which he doesn't do.
Beauty Contest: One of the sideplots in the fifth book is Mae and Chuck going undercover at a beauty pageant where one of the contestants is thought to be the next target.
Bedsheet Ladder: Olivia and Mae use one per book, first time to get out of Mae's house to go on a rogue investigation, the second time to break out of house arrest from Detective Madison's apartment, the third time to go to the crime scene in the middle of the night, the fourth time to go see the body in the middle of the night. Apparently, Olivia keeps one on standby.
Broken Bird: Detective Madison eloped with her boyfriend, got knocked up, found out he was cheating on her, kicked him out, and is now a single mother. Mae's little sister was killed, the first victim of the serial killer, and she never knew why her sister died.
Bunny-Ears Lawyer: Detective Madison is said to only be allowed to do the things she does because she does what she's supposed to do so well. Heyrovsky, Olivia and Liam's English teacher, is a much straighter example. He's barefoot, a hippie, old, probably stoned or drunk, and only allowed to teach because he has a doctorate in English literature.
Butt Monkey: Detective Larson always ends up listening to people's relationship rants, much to his dismay. Chuck steals his credit card, Olivia steals his breakfast, and nobody particurally likes him.
Poor Communication Skills: Landon and Cassie. Half of their major relationship problems could be avoided if Landon listend and Cassie communicated.
Pregnant Badass: Detective Madison in the third book. And fourth book. And fith book.
Promotion to Parent: Landon Simon, after he, Olivia, and Chuck's mother passed away and their father ran away.
Screaming Birth: Played straight by Detective Madison (though justified since she was shot in the ovary, which induced labor), and averted by Sam, who was calm enough to talk Chuck through how to help her give birth.
"Shut Up" Kiss: Justin to Olivia, right before she is about to go meet the killer.
Tagalong Kid: Technically, all of the main characters under the age of 15, but Kate and Chuck tagalong the tagalongs.
