Why could he only find her when she appeared as Flame?

Tyler McMann—contractor by day, Dom by night. Jenyfer Mayhew—accountant by day, sought-after sub by night. She's the masked Flame, the star of Finesse, an upscale private dungeon where the only numbers that count are how many strokes of the paddle a sub can take. Tyler is one of its best customers, a place where he can shuck the discipline of his work and indulge his fantasies. The chemistry between the two lights up the sky. But when he learns her real identity, he has to work hard to keep her from running and realize she can truly depend on him.
