Sgarzi shrugged. “Things Shana said, alluded to. But also . . . Things Shana would know. Including about her fellow prisoners. Apparently, her little friend would research for her, because if anyone got in an argument with Shana, suddenly she would start making very specific threats. You know, stop humming that same goddamn song, or the next time your drunken whore of a mother takes your six-year-old son to Billy Bear’s day care, they’ll both be sorry. Crap like that. But very detailed crap. Enough so, the other girls did what Shana said. She spooked them then, she scares them now. I’m not kidding. Research among yourselves. Shana’s rep reaches far beyond prison walls. She may have her sister and all the prison officials thinking she’s some depressed lonely soul, but take it from me, it’s all an act. She’s running the biggest con in MCI history. Pathetic prisoner by day. Homicidal genius by night.”

D.D. stared at Sgarzi. She didn’t know what to say. She didn’t know what to think.

“One hundred and fifty-three,” Phil said.

“What?”

“One hundred and fifty-three. You’re the supposed expert on Shana Day. Tell us what that number means.”

Sgarzi frowned at them. “Hell if I know.”

“You research Harry Day, Shana’s father?”

“Course.”

“Then, what did it mean to him?”

“You mean, like a lucky number?”

“Was it?”

“Beats me. I’ve never run across mention of a lucky number before.”

“Address?” D.D. asked. “Significant to him or his victims?”

Sgarzi shook his head, looking as confused as they felt.

“What about for Shana?” D.D. pressed. “Your cousin, her foster family, where did they live?”

“Not at one hundred and fifty-three anything.” Sgarzi’s gaze suddenly sharpened. “So what’s the significance? Is it a clue from the Rose Killer? A code you have to crack? I can work on it. First dibs on the story, though. Full quid pro quo.”

“Please,” D.D. informed him. “You gotta pay to play, and so far, you haven’t told us anything we didn’t already know.”

“I gave you Shana’s friend.”

“What friend? You mean her imaginary friend? The one she talks to but no one has ever seen? You might as well have told us to track down Casper the Friendly Ghost.”

“She’s got eyes and ears beyond prison walls.”

“Already knew that.”

“She spies on her sister.”

“Knew that, too.”

“Really?”

“Dr. Glen isn’t as dumb as she looks. Wait, she looks plenty smart. And she is a professional psychiatrist with few illusions about her own gene pool. Come on. We want something good. Why do you think Shana is connected to the Rose Killer?”
