magnesium, phosphorus, sulfur, calcium carbonate, and soluble silver in the form of silver nitrate. Some of the others, like water, clover, salt, and cocoa, would be easy.
“Dan, what are you doing?” Amy’s voice suddenly called from the doorway.
Dan jumped. “Come on in, the door’s open, thanks for knocking.”
“I wanted to talk about Jake,” she said softly.
“Oh, great,” Dan grumbled. “Mr. Congeniality.”
“He’s so angry all the time. I can’t bring myself to show him the text from …” Amy’s eyes locked on the phone, resting on the carpet. Its screen glowed with the text from AJT. She sighed.
Dan scowled. “Here comes the lecture.”
She sat on the floor next to him. “Dan, Dad was a Cahill. Through and through. Even if he wasn’t born one. I wish you could remember his eyes. When you were little, he’d hold you up to everyone and say -”
“‘
“You both would flash this big, identical grin,” Amy said. “Mom said you were twins separated by a generation. The man wasn’t capable of evil. His life was not a lie. If you really knew him, you’d never say the names
“People lie, Amy,” Dan protested. “People pretend -”
“Dan, there were two bodies in the fire,” Amy insisted. “No one could have lived through that. Besides, if he were alive, he’d be with us. He wouldn’t have stayed away from the Clue hunt. He would have led it.”
Dan spun around. “The bodies were burned beyond recognition. They could have been anybody. Uncle Alistair survived a cave collapse, Amy! Cahills do things like that. And if Dad tried to save Mom, then watched her burn to death – in a fire set
Amy’s face drained of color. “What are you saying, Dan?”
“Remember Grace’s note – the one we found after discovering the secret to the clues?” Dan said. “She said the Cahill family was broken. Untrustworthy. Isabel set the fire, and no one helped out – the Holts, Uncle Alistair, none of them. I’m saying Dad would have seen them for what they are. Murderers.”
Amy’s face darkened. “So you think he went over to the dark side, just like that?”
“He would have seen it the opposite way, Amy,” Dan said. “The dark side was what he left.”
Amy reared back her hand to slap Dan. He reeled in shock.
Before she could move, a beep sounded from Dan’s smartphone.
They both froze.
Dan stooped to pick up the phone and noticed a blinking icon across the top of the screen. A GPS signal. He opened the app and saw a signal moving across a map of western Europe. Its origin was RUZYNE AIRPORT, PRAGUE. It was moving east.
Along the bottom was the name A. ROSENBLOOM.
“Wake up and smell the limestone,” said Cheyenne Wyoming, yanking the blindfold from Atticus’s face.
He blinked. On the plane, hours earlier, he had lined up his worst fears – torture, plane crash, poisoning, being shoved out at thirty thousand feet.
Waking up at Site Number Seven on his Cool World Travel Wish List would not have been anywhere near the top.
Awestruck, he stared into a scene of lopsided, cone-shaped mountains, like giant castles made of dripping wet sand. “We’re in Goreme, Turkey?” he said, his voice still froggy from a forced sleep.
“You’re familiar with this dump?” Cheyenne said.
“In actuality,” Atticus said, “it’s one of the most interesting geological formations on the planet. If I weren’t with you, I’d be running around like, woo-hoo -”
Casper pushed him hard. Atticus stumbled forward, his sleepy eyes focusing. His brain suddenly connected with something that had been dulled by sleep.
His terror.
Bread truck. Sack. Handcuffs. Jet. It all rushed back.
They had knocked him out on the plane. Cheyenne insisted on it. She was afraid he’d get sick.
He glanced around for a way to escape. He was no longer handcuffed, but there was nowhere to run. It looked as if they were in a vast moonscape, the monstrous rock formations casting deep shadows in the afternoon sun. He’d seen photos, but in person they were much bigger – like giant rock fingers poked through with enormous holes. Caves.
They were heading toward the largest rock, shaped like a sinking ship. At its base, an ominous-looking sign had been tied to a trash can:
Atticus rubbed his eyes, recalling his years of online language tutorials. “Wait, that’s Turkish,” he murmured. “And it means ‘Danger: Collapsed Cave.’ ”
“Don’t believe everything you read,” Cheyenne said.
She shoved him in before he could protest. He hit his head and had to duck low to fit through. His ankle twisted as it landed between two wooden planks, rotted and termite-eaten. Cheyenne scampered on ahead, waving a flashlight.
“I can’t see!” Atticus said.
“Casper, where are you?” Cheyenne called over her shoulder.
“Emptying my pockets.” Another flashlight beam, behind Atticus, began illuminating the planks. “A trash can outside. All the convenience of home.”
Atticus stumbled along, his head scraping the low ceiling. “Wh-where are you taking me?”
“To a place where we can talk in private.” Cheyenne stopped short. She gestured into a corner of the cave, sweeping aside a thick spiderweb. “Go.”
Atticus peered into the pitch darkness. The cave seemed to end there, a tiny, dank chamber big enough for one person. Nothing beyond. Just a cranny in a cave where a dead body could rot and no one would ever see it.
Cheyenne pushed him in. As his back hit the cragged wall, she and her brother crowded close to him. A light blinked on above, bathing them all in a greenish white glow. “Unrecognized DNA,” a mechanical voice droned.
“Allow access!” Casper called out.
A series of beeps was followed by “Voice recognition accepted.”
The ground rumbled. With a loud scraping noise, the floor beneath their feet began to move. They were on a circular platform, slowly sinking.
“No!” Atticus reached for the lip of the floor, but Casper batted his arms away. Bright lights flickered on below their feet, and soon the cramped, stinking cave gave way to a vast underground chamber.
The place was freezing. Enormous maps spanned the walls. A news ticker scrolled headlines near the ceiling. A bank of clocks ticked in unison, telling time in different parts of the world to the thousandth of a second. Brushed- steel cabinets lined the walls near empty computer workstations, their black, webbed chairs gathering dust.
The platform reached the chamber floor with a dull thump. Casper grabbed a chair. “Make yourself at home.”
Atticus sank into the chair, sending up a small cloud of wispy dust. His throat was dry. He had to swallow twice before he could eke out a sound. “What am I supposed to do?”
Cheyenne pulled a handkerchief from her bag and dusted off two seats. The twins sat. “Tell us what you know.”
“About what?” Atticus asked.
Cheyenne glanced at her brother, rolling her eyes. “The genius thinks he’s too smart for us nincompoops.”
Atticus screamed. His leg dug reflexively into the floor, propelling the chair backward. He crashed against a computer table, the impact knocking the wind out of him.
Casper cracked up. “Brave kid.”
“I suggest cutting to the chase,” Cheyenne said, looking brightly around the room. “No one can hear you in here. No one knows where you are. You will not leave until you answer. And you will not live if you don’t.”
