Stealing a Thief's Heart

And Keeping It

Prologue: Introducing the Players

Nico di Angelo smiled softly and took a sip of his coffee.

His job was annoying and irritating most of the time. Being CEO of the 'Elysium Agency for Young Talents', the biggest agency in Los Angeles, was sometimes making him want to jump down a bridge. Or push some of the people who thought they were talented down a bridge. He spend nearly the whole day in his office, but once he got out, everything seemed to brighten. There was that little café on the other side of the street, called 'Hestia's Hearth'. The coffee tasted horrible, but the waiter was completely making up for that. The boy was stunningly beautiful. The most mesmerizing and unique sea-green eyes, full, rosy lips that looked way too kissable and so stunning when he smiled. And the teen's ass was perfection. He should know, his family owned a big collection of ancient Greek art, including some perfectly sculpted Greek boys. But that boy, he looked like a Greek hero himself. So perfect. And if Nico wouldn't have a perfect boyfriend already, he would have swept that teen off his feet and took him months ago.

"Can I get you something else, Mister di Angelo?", wanted the boy to know with a soft smile.

"Please don't call me a mister, Percy. That makes me feel old", smiled Nico. "I told you, my name is Nico. But no, I'm content for now, I'll have to leave soon anyway."

The boy was nineteen, had graduated high school only a few months ago in New York, the city he had never left before his graduation. But then he had left for the city where dreams came true. Since then he was working as a waiter at the 'Hestia's Hearth'. Sometimes it came in handy to be rich, that made paying a private eye so much easier. Okay, so his boyfriend was probably right that he was a creepy stalker and that Percy would do right to get a restricting order against him, but it wasn't Nico's fault that this boy was so captivating. If Jason would finally take the time to go and drink a coffee with him, then he would see for himself how special Percy Jackson truly was.

Percy Jackson grunted irritated and ran down the alley.

His shift had been over for over an hour already when Nico di Angelo had come in, but Percy couldn't, not for the life of him, go without seeing the charming Italian. In a city full of people who thought they were better than anyone else, this man was probably the only one who treated him with respect and was actually nice to him. Most costumers were grumpy and mean, letting their frustrations over their shattered dreams out at him. But the CEO was so friendly, asking him about his day, just conversing with him as if he was an equal human being. Even though Percy wouldn't say that. Because Nico di Angelo was one of the richest people in the states. And certainly one of the hottest. A stupid grin spread over his lips at the thought of the tall and lean Italian with the dark, piercing eyes and the messy hair, that looked as if the CEO just had really good sex with his lover clawing at the hair. Percy liked picturing himself as that. As the lover that got held by the strong arms, the rich voice whispering lovely nonsense in the most romantic language he had ever heard (everything sounded way too puffy in French, Italian was the hotter language for him).

Shaking his head to get those distracting thoughts out of his head, he stripped down, having the clothes of his second work right under the annoying orange uniform. A wicked grin tugged on his lips as he put the last piece on. The blue Venetian mask. Tying it at the back of his head, he jumped up the stairs, the museum finally entering his view. Time to visit his second sweet-heart, the handsome detective by whom he would love to get handcuffed in any other situation. If only not in the situation they found themselves in whenever they met...

Detective Jason Grace sighed exhausted and took a look around.

The curator of the museum – his boyfriend's younger half-sister Hazel Zhang – was constantly frowning and pacing the room, her high-heels making a clicking sound on the marble. Her husband was trying to calm her down. But Detective Frank Zhang was having a hard time doing so, since his partner Clarisse la Rue was currently occupying his ear with one of her famous rants about how that stupid little thief was making a fool out of them all and they would certainly catch him this time.

"Jason!", called his own partner, pulling him out of his thoughts. "He's here."

"Damn it", growled the blonde detective and turned to his partner.

Jason scolded at that. The little nuisance that kept him awake at night (and for once he wasn't talking about his horny boyfriend). The thief best known as the 'Black Siren'. Just thinking that name made him furious. Those skin-tight black leather pants, showing that perfectly shaped ass off like that, and the formal black dress-shirt. But the most remarkable thing about Black Siren were his eyes. Never before had he seen such a deep and bright sea-green, framed by an old fashioned Venetian mask, the thing that had become his trademark, with silver and gold emblems and jewels, aquamarines and sapphires, pearls and emeralds, underlining how stunning those eyes were.

"Hello, my dear detective", purred a seductive voice into his ear.

He stiffened and whirled around, just to stare into those eyes. They were hypnotizing. Gritting his teeth, he tried to reach for the thief, just to find him exactly out of reach. Just as always. The slightest bit out of his reach. But he swore to himself, one day he would capture the Black Siren.

One day the thief would be his.
