“The electronic calendar is bullshit,” he interrupts. “All this automated instant bullshit. I just wish Lucy would give it a rest. You know what you need to know, that someone’s doing what they’re supposed to. That someone being me.”

“I’m not aware that the head of investigations is on call. That’s never been our policy, unless there’s an emergency. And it’s also not our policy to be a firehouse, to sleep over on an inflatable bed while waiting for an alarm to clang, so to speak.”

“I see someone’s been narking. It’s her fault, anyway.” He puts his sunglasses on, wire-frame Ray-Bans he’s worn for as long as I’ve known him—what Bryce calls Marino’s Smokey and the Bandit shades.

“The investigator on call is supposed to be awake at his or her work station, ready to answer the phone.” I say this evenly and with no invitation for the argument he is giving me. “And what is whose fault?”

“Fucking Lucy got me on Twitter, and that’s what started it.”

When he says “fucking Lucy” I know he doesn’t mean it. The two of them are close.

“I don’t think it’s fair to blame her for Twitter if you’re the one tweeting, and I understand you have been,” I reply in the same bland tone. “And she didn’t exactly nark on you, or some things I would have known before now. Anything she’s said, it’s because she cares about you, Marino.”

“She’s out of the picture and has been for weeks, and I don’t want to talk about it,” he says, as we slowly descend through the center of the building.

“Who is?” I puzzle.

“The twat I was tweeting, and that’s all I have to say about it. And you really think people don’t sleep when they’re on call? I didn’t miss nothing last night. Every time the phone rang, I answered it and handled it. The only real scene to respond to was the guy who fell down the stairs, and Toby took care of it, a cut-and-dried accident. Then I sent him home. No point in both of us being there. And besides, he gets on my nerves. I can never find him where he’s supposed to be, either that or he’s on top of me.”

“I’m just trying to understand what’s going on. That’s all. I’m making sure you’re okay.”

“Why wouldn’t I be?” He stares straight ahead at smooth shiny steel, at the illuminated LL on the digital panel. “I’ve had things not work out before.”

I have no idea what things or who he’s talking about, and now is not the time to press him about some woman he met on the Internet, or at least this is what I suspect he’s alluding to. But I do need to talk to him about what I worry could be a breach of professional discretion and confidentiality.

“While we’re on the subject, I’m wondering why you went on Twitter to begin with, or why Lucy supposedly might encourage such a thing,” I say to him. “I’m not trying to pry into your personal life, Marino, but I’m not in favor of social networking unless it’s primarily for news feeds, which is the only thing I follow on Twitter. Certainly we aren’t in the business of marketing what we do here or sharing details about it or making friends with the great outdoors.”
