FBI Agent Burt, Japp and others in “Unfinished Business”

Japp, I hope you're not so short of manpower you're hiring a shamus. What are they good for, chasing lost dogs? This is a matter of international security we're dealing with here.

I have no intention of hiring anyone, Burt. And if you must know, Mr. Poirot here has an outstanding reputation.

Oh! A gumshoe of distinction. And I suppose Al Capone's running for president.
