The Lightning Thief

muttered something I couldn’t make out, probably “Don’t let them in!”
    Sadie closed the door and regarded me as if I were a dead mouse her cat had just dragged in. “So, here you are again.”
    “Yep.”
    “Come on, then.” She sighed. “Let’s get on with it.”
    That’s the way she was. No “Hi, how you been the last six months? So glad to see you!” or anything. But that was okay with me. When you only see each other twice a year, it’s like you’re distant cousins rather than siblings. We had absolutely nothing in common except our parents.
    We trudged down the steps. I was thinking how she smelled like a combination of old people’s house and bubble gum when she stopped so abruptly, I ran into her.
    “Who’s that?” she asked.
    I’d almost forgotten about the dude in the trench coat. He and my dad were standing across the street next to the big tree, having what looked like a serious argument. Dad’s back was turned so I couldn’t see his face, but he gestured with his hands like he does when he’s agitated. The other guy scowled and shook his head.
    “Dunno,” I said. “He was there when we pulled up.”
    “He looks familiar.” Sadie frowned like she was trying to remember. “Come on.”
    “Dad wants us to wait in the cab,” I said, even though I knew it was no use. Sadie was already on the move.
    Instead of going straight across the street, she dashed up the sidewalk for half a block, ducking behind cars, then crossed to the opposite side and crouched under a low stone wall. She started sneaking toward our dad. I didn’t have much choice but to follow her example, but it made me feel kind of stupid.
    “Six years in England,” I muttered, “and she thinks she’s James Bond.”
    Sadie swatted me without looking back and kept creeping forward.
    A couple more steps and we were right behind the big dead tree. I could hear my dad on the other side, saying, “—have to, Amos. You know it’s the right thing.”
    “No,” said the other man, who must’ve been Amos. His voice was deep and even—very insistent. His accent was American. “If I don’t stop you, Julius, they will. The Per Ankh is shadowing you.”
    Sadie turned to me and mouthed the words “Per what ?”
    I shook my head, just as mystified. “Let’s get out of here,” I whispered, because I figured we’d be spotted any minute and get in serious trouble. Sadie, of course, ignored me.
    “They don’t know my plan,” my father was saying. “By the time they figure it out—”
    “And the children?” Amos asked. The hairs stood up on the back of my neck. “What about them?”
    “I’ve made arrangements to protect them,” my dad said. “Besides, if I don’t do this, we’re all in danger. Now, back off.”
    “I can’t, Julius.”
    “Then it’s a duel you want?” Dad’s tone turned deadly serious. “You never could beat me, Amos.”
    I hadn’t seen my dad get violent since the Great Spatula Incident, and I wasn’t anxious to see a repeat of that , but the two men seemed to be edging toward a fight.
    Before I could react, Sadie popped up and shouted, “Dad!”
    He looked surprised when she tackle-hugged him, but not nearly as surprised as the other guy, Amos. He backed up so quickly, he tripped over his own trench coat.
    He’d taken off his glasses. I couldn’t help thinking that Sadie was right. He did look familiar—like a very distant memory.
    “I—I must be going,” he muttered. He straightened his fedora and lumbered down the road.
    Our dad watched him go. He kept one arm protectively around Sadie and one hand inside the workbag slung over his shoulder. Finally, when Amos disappeared around the corner, Dad relaxed. He took his hand out of the bag and smiled at Sadie. “Hello, sweetheart.”
    Sadie pushed away from him and crossed her arms. “Oh, now it’s sweetheart, is it? You’re late. Visitation Day’s nearly over! And what was that about? Who’s Amos, and what’s the Per Ankh?”
    Dad stiffened. He glanced at me like he was wondering how much we’d overheard.
    “It’s nothing,” he said, trying to sound upbeat. “I have a wonderful evening planned. Who’d like a private tour of the British Museum?”
     
    Sadie slumped in the back of the taxi between Dad and me.
    “I can’t believe it,” she grumbled. “One evening together, and you want to do research.”
    Dad tried for a smile. “Sweetheart, it’ll be fun. The curator of the Egyptian collection personally
