Inspector Japp
A Scotland Yard man who trades official procedure for Poirot's inconvenient habit of being right.

Also known as Japp, the good Japp
First appearance: the adventure of the western star
As a supporting figure in Poirot Investigates, Inspector Japp is not background color—the story leans on what they do once the chapter opens.
Mentioned as waiting outside the window during the séance, tapping to create ghostly effects.
Japp is the professional policeman whose cases keep colliding with Poirot's amateur genius, and he knows better than to resent it. He brings the weight of the Yard but yields the final word to the little Belgian, a working partnership built on grudging respect. His presence grounds the stories in real police machinery, making Poirot's leaps feel like triumphs over method rather than mere cleverness.
