do a vanishing act

To depart or go away very suddenly or without warning, especially so as to avoid doing or dealing with something. My roommate loves to throw parties here, but she always does a vanishing act the next day when everything needs to be cleaned up! Brian is nearly two weeks late finishing his sales report—that's why he's been doing a vanishing act whenever the boss is around.
