Already, a familiar exhilaration has my skin beginning to glow. This is the chance to potentially help an old lady out and punish the worst kind of criminal—one who preys on his own family.

Temper notices my glowing skin, her gaze transfixed. She reaches out before she remembers herself. Not even she is immune to my glamour.

She shakes her head. “Girl, you are a twisted motherfucker.”

That is God’s honest truth.

“Takes one to know one.”

She snorts. “You can call me the Wicked Witch of the West.”

But Temper’s not a witch. She’s something far more powerful.

She checks her phone. “Shit,” she says, “I’d love to stay and chat, but my perp’s going to be at Luca’s Deli in less than an hour, and with L.A. lunch hour traffic … I really don’t want to be forced to part the 405 like the Red Sea. Shit like that looks suspicious.” She stands, shoving her phone to her pocket. “When’s Eli getting back?”

Eli, the bounty hunter who sometimes works for us and sometimes works for the Politia, the supernatural police force. Eli, who’s also my boyfriend.

“Sorry Temper, but he’ll be gone for another week.” I relax a little as I say the words.

That’s wrong, right? To enjoy the fact that your boyfriend’s gone and you get time alone?

It’s probably also wrong to find his affection stifling. I’m afraid of what it means, especially because we shouldn’t be dating in the first place.

First rule in the book is to not get involved with colleagues. One evening of afterwork drinks six months ago, and I broke that rule like it’d never been there in the first place. And I broke it again, and again, and again until I found myself in a relationship I wasn’t sure I even wanted.

“Ugh,” Temper says, her ’fro bouncing a little as she leans her head back, her eyes moving heavenward. “The bad guys always love to stir shit up when Eli’s gone.” She heads for my door, and with a parting look, she leaves my office.

I stare at the file a moment, then I pick it up.

The case isn’t anything special. There isn’t anything particularly cruel or difficult about it. Nothing to make me reach for the Johnnie Walker I keep in one of my desk drawers. I find I want to anyway, that my hand itches to pull the bottle of it out.

Too many bad people in this world.

My eyes flick to the onyx beads that coil around my left arm as I drum my fingers against the table. The beads seem to swallow the light rather than refract it.

Too many bad people, and too many memories worth forgetting.

The swanky restaurant I walk into at eight p.m. sharp is low lit, candles flickering dimly from each two-seater table. Flamencos is clearly a place rich people come to romance each other.

I follow the waiter, my heels clicking softly against the hardwood floor as he leads me to a private room.

Twenty grand. It’s a crap ton of money. But I’m not doing this for the payout. The truth is that I’m a connoisseur of addictions, and this is one of my favorite.

The waiter opens the door to the private room, and I enter.

Inside, a group of people chat amicably around a large table. Their voices quiet a little as soon as the door clicks shut behind me. I make no move towards the table.

My eyes land on Micky Fugue, a balding man in his late forties. My target.

My skin begins to glow as I let the siren in me surface. “Everybody out.” My voice is melodious, unearthly. Compelling.

Almost as one, the guests stand, their eyes glazed.

This is my beautiful, dreadful power. A siren’s power. To compel the willing—and unwilling—to do and believe whatever it is I wish.

Glamour. It’s illegal. Not that I really give a damn.

“The evening went great,” I tell them as they pass. “You’d all love to do this sometime in the future. Oh—and I was never here.”

When Micky walks by me, I grab his upper arm. “Not you.”

He stops, caught in the web of my voice, while the rest of the guests file out. His glazed eyes flicker for one moment, and in that instant, I see his confusion as his awareness fights my strange magic. Then it’s gone.

“Let’s sit down.” I direct him back to his seat, then slide into the one next to him. “You can leave once we’re finished.”

I’m still glowing, my power mounting with every passing second. My hands tremble just the slightest as I fight my other urges—sex and violence. Consider me a modern day Jekyll and Hyde. Most of the time I’m simply Callie the PI. But when I need to use my power, another side of me surfaces. The siren is the monster inside of me; she wants to take, and take, and take. To wreak havoc, to feast on her victims’ fear and lust.

I’d be hard-pressed to admit it out loud, but controlling her is hard.

I grab a piece of bread from one of the baskets at the center of the table, and I slide over a small plate one of the guests hasn’t touched. After I pour olive oil, then balsamic vinegar onto the plate, I dip the bread into it and take a bite.

I eye the man next to me. That tailored suit he wears hides the paunch of his belly. On his wrist he wears a Rolex. The file said he was an accountant. I know they make decent money, especially here in LA, but they don’t make money this good.

“Why don’t we get right to the point?” I say. As I talk, I set up my phone so that the camera records our exchange. For good measure I pull out a handheld tape recorder and turn it on.
