Dirty Details Done Dirt Cheap:
Dr. Gillian Foster is based on Professor Maureen O'Sullivan, a psychology professor at the University of San Francisco. Gillian is a skilled psychologist and the professional partner of Dr. Cal Lightman of The Lightman Group. In detecting lies through facial expressions, body language and other subtle nuances, Gillian is able to see the "big picture" of the situation in contrast to Lightman's obsession with details. She and her husband adopted an infant girl named Sophie but the child's birth mother took her back after 57 days; this incident and her husband's secretive nature as a recovering drug addict put a strain on their relationship and they have since separated. Gillian's guilty pleasures include romance novels and pudding.
