That reminds me of an old Sidney Sheldon book called If Tomorrow Comes (it was also a mini-series). The main character, Tracy, is a jewel/art/antique thief. She ends up falling in love and working with her main "competitor" (a man named Jeff). They are planning a huge heist in a foreign country (France, I think). The police have their hotel room bugged. For weeks, the police are getting all the scoop on this big heist. Come the day of the heist, the police are all in place, ready to arrest Tracy and Jeff, but they are nowhere to be found.
Turns out, Tracy and Jeff knew of the bug and were giving details of fake plans. While all of the cops were camped out waiting for the fake heist, Tracy and Jeff were doing their real heist, miles away.
