Friday in Las Vegas by Kaye Hopkins

When Isabel Morgan washes out of the police academy because of a deeply humiliating trait she wasn't aware of (she can't fire a weapon without closing her eyes), she discovers the world of crime and trauma scene cleaning. Enlisting the help of her roommate, Kenny Diaz, she starts her own cleaning business.

One of Izzy and Kenny's first jobs is a possible murder/suicide at The Kingdom Hotel and Casino in Las Vegas, Nevada. As it turns out, this is one of her father's cases. He is a homicide detective with the Las Vegas Metropolitan Police Department and wanting to be closer to her dad and his world, Izzy begins her own investigation---an investigation that puts her in the sights of one violent and vindictive security guard. But when she's kidnapped and thrown into a dungeon-like room at the casino, she finds that guard beaten up and half dead.

So, who is the real enemy here? Could it be Devlin Russo the young handsome manager of The Kingdom with possible mob connections and the man she's just fallen for? Could it be someone she hasn't even met yet? And is she going to end up in the same condition as the security guard or are they both going to die, buried beneath tons of concrete, in a room where no one can hear you scream?
