Welsh Canadian foodie and criminologist Cait Morgan takes off on a short break to the fabulous Tsar! Casino and Hotel in Las Vegas with her significant other, retired cop Bud Anderson. But before they can start celebrating Bud's birthday in style at the casino owners' exclusive private dining room, the death of Miss Shirley -- a woman with a colorful background and the acknowledged Queen of the Strip -- results in a security lockdown. Cait, Bud, a corpse, and ten possible murderers are trapped in the luxurious restaurant for twelve deadly hours. The bodies pile up, the tension mounts, the list of suspects dwindles -- and Cait knows she has to work out who within the group is an audacious killer because there's no telling who might be next to die.
