Contessa Montenegro.

Hungarian-accented KAOS agent whose main concern appears to be making it clear that her drink of choice is not a Martini but a Manhattan.

The Contessa is murdered by Milton Conrad with a booby-trapped makeup compact to prevent her from defecting to British agent Colonel Roger Forsythe.

Portrayed by Maureen Arthur [Episode #38: "Hoo Done It"].

Reality Check: Any resemblance between the Contessa and the Gabor sisters is of course purely coincidental.
