The key to the Inspector's house is given to you by the museum curator after you chase the thief on Counterfeit Island. The sign is rather obvious, since "Veuve Noire" is French for Black Widow (it is misspelled 'niore').
(After the scooter chase, get the package at the museum. Do what it says and you'll get the key to her house.)
