Cecily Burkett was the live-in girlfriend of David Nicolaides, and a mother-to-be. She was part of the small unit of those close to Balthazar Wolf, the "Big Bad Wolf" of the almost-unattainable restaurant, Q3. Castle himself noted that he couldn't manage to swing a reservation for the place. When Balthazar turned up dead in his own kitchen, it placed a question mark over many things, not least the future of the restaurant. However, the owner, Madison Queller, had had the foresight to take out business insurance, a fact which, for some time, made her a suspect.
