Or that annoying father and son combo who came to look at the vase, and I'm also tempted by the guy at Yomiuri television who dragged Mouri, Ran and Conan into the Seance murder case -- geez, I watched it just last night and have forgotten the name already.

Anyway, for my memory as much as any other reason, girl who works in Poirot is Azusa Enomoto, and her brother is Sugihito Enomoto. The obnoxious father and son don't seem to have been named, although Haibara never met them, so maybe we should forget them and go with an acquaintance of the Professor's, and the TV dude is Yatsukawa-san.
