Artemis Fowl and the Atlantis Complex by Eoin Colfer

red-jacketed doormen clustered around the automatic doors, nodding and smiling at the crowd hurrying in for the main event.
    Around the back, he decided. The story of my life .
    Butler skirted the building, thinking that it would be nice, just once, to go in the front door. Maybe he would in another lifetime, when he got too old for this business.
    How old do I have to be? he wondered. Come to think of it, with all the time travel and fairy healings, I’m not even sure how old I actually am anymore .
    As soon as Butler reached the back door, he put all other thoughts from his mind, apart from the job at hand. Get to Juliet, find out what trouble she was in, and extricate her with minimal collateral damage. There were still ten minutes before the show was scheduled to start, so with a little luck he could nab his sister before the room got too crowded.
    The only security on the back door was a single surveillance camera. Luckily, the Grand was a straight theater and not the convention room of a resort hotel, or there would have been a cluster of pools at the back door, along with crowds of tourists, a salsa band, and possibly half a dozen undercover private cops. As it was, Butler slid unnoticed into the theater and simply waved at the camera on the way in, effectively covering his face.
    Butler did not meet a shred of opposition on his way through the theater’s backstage area. He passed a couple of costumed wrestlers sharing an electrolytic drink, but they barely spared him a glance, probably assuming he was one of them. Big and dumb, by the look of him—the bad guy.
    Like most theaters, the Grand had miles of corridors and back passages that had not shown up on the blueprints Butler had downloaded on his smartphone from Artemis’s interpedia, which had a dedicated blueprint site containing any plans that had ever been uploaded and quite a few that Artemis had stolen and uploaded himself. After several wrong turns, even Butler’s excellent sense of direction was failing him, and the big bodyguard was tempted to simply punch through walls and create the shortest route to where he wanted to go: the performers’ dressing room.
    Butler finally arrived at the dressing room door just in time to see the tail end of the wrestling squad winding their way through to the stage, looking like sections of a Chinese dragon in all their Lycra and silk. After the last wrestler slipped through, a barrier of meat and muscle in the shape of two enormous bouncers closed across the backstage doors.
    I could take them, thought Butler. That would not be a problem, but it would only leave me seconds to find Juliet and get her out of here, and, knowing my sister, she will want to conduct a complicated and ultimately meaningless conversation before she’s ready to go. I need to think like Artemis, like the Artemis of old, and play this calmly. Blundering in is likely to get both of us killed.
    Butler heard the howls and whoops of the crowd as the wrestlers entered. The noise was muffled through the double doors, but clearer from the dressing room. He poked his head inside and saw a monitor bracketed to the wall, displaying the action in the ring. Convenient.
    Butler stepped close to the screen and searched for his sister. There she was, at the corner of the ring, performing some ostentatious warm-ups that were more for show than actual effect. If Butler could have seen his own normally taciturn features at that moment, he would have been surprised by the fond, almost sleepy, smile that lingered on his face.
    It’s been too long since I’ve seen you, little sister.
    Juliet did not seem to be in any immediate danger; in fact, she appeared to be relishing the crowd’s attention, raising her arms for more applause and whipping the jade ring on her ponytail around in figures of eight. The crowd loved her too. Several young men waved banners bearing Juliet’s image, and a few were bold enough to shower her with confetti hearts. Butler frowned. He
