This looks to be an interesting series: The Magician’s Daughter: A Valentine Hill Mystery by Judith Janeway

Magician Valentine Hill always introduces her act by announcing “Reality is an illusion. Illusion is reality, and nothing is what it seems.” When Valentine is reunited with her grifter mother, “nothing is what it seems” becomes true in real life. A wealthy socialite turns out to be a ruthless criminal, a car mechanic a psycho killer, and a cab driver a seductive gangster. When an FBI agent who’d befriended her is killed, Valentine takes on the hated role of a con artist to get evidence to put the criminals away. Will her skills as a magician prove enough to help her maintain the illusion?
