“She was hit over the head and asphyxiated, probably raped,” Cassie said. The fluorescent lighting smudged gray under her eyes. She looked too tired and too young to be saying the words so calmly. “We won’t know anything definite till the post-mortem tomorrow morning.”

“Fucking tomorrow?” O’Kelly said, outraged. “Tell that shite Cooper to give this priority.”

“Already did, sir,” said Cassie. “He had to be in court this afternoon. He said first thing tomorrow is the best he can do.” (Cooper and O’Kelly hate each other; what Cooper had actually said was, “Kindly explain to Mr. O’Kelly that his cases aren’t the only ones in the world.”) “We’ve identified four primary lines of inquiry, and—”

“Good, that’s good,” said O’Kelly, grabbing drawers open and rummaging for a pen.

“First, there’s the family,” said Cassie. “You know the stats, sir: most murdered kids are killed by their parents.”

“Second,” she said, “we’re going to have to at least check out the possibility of some kind of cult.”

“Oh, God, Maddox. What, did Cosmo run an article on Satanism this month?” O’Kelly’s disregard for cliché is so sweeping that it almost has its own panache. I find this entertaining or irritating or mildly comforting, depending on my mood, but at least it makes it very easy to prepare your script in advance.
