Gallagher Girls :

Cammie Morgan, Macey McHenry, Rebecca Baxter, Elizabeth Sutton and Zachary Goode are the detectives involved.

The series is set "mainly in the USA, slightly more specifically: Gallagher Estate outside Roseville, Virginia (but they get to Boston and London and other places)

This is a ya spy series, not a pure detective series, but Cammie and her friends do have to put the pieces together to protect the school, the country, and the world from devious plots (which seem to have a common origin)"

Hercule Poirot :

Hercule Poirot solves murders -and mysteries- in England, with the occasional participation of the Captain Arthur Hastings and Inspector Japp.
