"We can't go back," Linda said. "He'll be waiting."
"Well, then maybe we can find another way back to Alpha Base. One of the side tunnels," Blakely said, his voice wheezing in the smoky air, his eyes red and watering.
Jason looked back the way they had come. Pinching his nose against the stench, he watched the whorls of black smoke fly away from him, smoke that stank like roasted rubber tires. He could even taste its foulness on the back of his tongue. The dampened cloth wrapped around his face did little to stop the stench.
Still, no one complained, since the smoke was also their guide. For the past day, whenever they had reached a crossroads in the tunnels, pausing to decide which way to go, the smoke wafting through the passageways marked the correct path.
"Turn around? I don't know," Linda said behind him. "None of the other passages had a breeze. The air seemed stagnant."
"What other choice do we have? We can't go forward." The doctor coughed harshly. "And at least we'd get away from this damned smoke."
Jason crossed to Linda's side. "Maybe I can wiggle past the hole."
Linda gave him a weak smile. "No, honey, it's too small."
"Let me see," Jason said, squeezing between Linda and Blakely. He coughed when he got a whiff of the thick smoke coming from the opening.
Blakely put an arm around him. "Hold up, Jason. We don't know how stable that is. Besides, Linda's right. It's much too small."
Jason persisted. "Just let me see!" He shoved past Blakely's hand and crouched down. The column of smoke looked like a solid pillar jetting toward him from the opening. Pushing a fist into it, he was amazed at the pressure of the wind, like sticking his hand out of a speeding car. But his amazement turned quickly to nausea as his probing arm disrupted the flow, diverting a stream directly into his face. Gagging, he pulled his hand back out. Lights twinkled before his eyes as he gasped for clear air.
Blakely placed a hand on his shoulder, a half-amused smile on his lips. "Careful, boy, that's potent enough to kill you."
His face reddening, Jason shrugged off his hand, now even more determined to investigate the hole. Before anyone could stop him, he sucked in a lungful of air and clamped his eyes and lips closed. Then he dove forward into the smoky wind.
He found himself almost instantly buffeted back by the pressure, but he dug his toes in beneath him. Working one arm and shoulder through the hole, he wiggled around, seeking a way to crawl ahead.
If he could just turn his head and twist over this way… but rock blocked him at every turn. In a few seconds, he realized it was much too small for him to squeeze through. Disappointed, he pulled back and rolled to the side, letting out his held breath in a long sigh.
He saw Blakely waving his hand before his nose as the disturbed smoke billowed around him. "A lot of good that did you. You almost gassed the two of us with your foolishness."
"But I was just-"
"Enough of this tomfoolery. We just need to accept our predicament and find an alternate route. This tunnel is a dead end for us."
Jason sniffed, trying to save face. "But I did find out that the hole is only about two feet deep. After that it widens again. I think the tunnel is fine beyond this short section. If we can find a way through…"
"Well, unless you happen to be hiding a pickax under your shirt, I'm afraid that's not much help."
Jason, finally defeated, hung his head.
Linda laid a consoling hand on his knee. "Hey, at least you tried. And besides, there's no harm done. Heck, if I had been any smarter, I could've stolen a cube of Khalid's plastic explosive. We could have blasted our way out." She lifted his chin with a finger. "I'm very proud of you."
Jason tried to suppress a smile but couldn't stop it. "Thanks."
She tousled his hair, then turned back to Blakely. "I guess we've no choice but to search for an alternate route."
Blakely mumbled something in response, but Jason had stopped listening. Instead, Linda's words repeated in his mind: Cubes? Explosives? He stood up. Could it be?
He crossed to where Linda huddled in conversation with Blakely and tugged on her sleeve. Linda glanced at him, and Blakely frowned down, his eyes narrowed with irritation at his intrusion.
"What is it, Jason?" she said, pushing back a strand of blond hair.
He shifted his feet. "Um, Linda, that explosive you were talking about. I think I may have some of it."
Blakely stepped forward. "What? How?"
Linda placed a restraining hand on Blakely's arm. "Jason, why do you think you have some explosive?"
Scuffing the toe of his sneaker on the rocky floor, not looking anyone in the face, Jason explained about the incident in the bathroom when Khalid's bag spilled into his cubicle. "I have it in my gym bag," he finished, pointing to the red Nike bag at his feet. "I'll show you."
He unzipped the bag and rummaged through it. He should have told someone. Now he was going to get into trouble. He shifted the contents of the pack around. It was difficult to search, full of gym clothes, an orange towel, a pack of playing cards that had fallen loose, and scattered loose change for the video-game machine. Where was it?
After a full minute, Blakely exclaimed in exasperation, "Just dump it on the floor." He tried to take the bag from Jason.
"Wait!" Jason pulled his Nintendo Game Boy from the bag. "It'll break." He shoved the Game Boy in his jacket pocket.
The doctor overturned the bag and shook it. All his stuff tumbled to the floor. The three of them searched through his loot.
Jason carefully tucked his spare pair of underwear out of sight, mortified that Linda might see his boxers. As he was hiding it under his towel, he spotted the familiar gray material.
Picking up the clay, he held it out to Linda. "Here it is."
With a whisper of a smile on her lips, she accepted the sculpted clay, eyeing his handiwork. "Nice airplane."
He shrugged. "I thought it was some sort of hard Play-Doh."
Blakely looked on with disbelief. "Are you sure it's the explosive?"
Linda fished a piece of crinkled cellophane from his belongings. "Yes, this is the same cellophane that wrapped the other cubes."
Blakely took the airplane from her as if handling the most fragile piece of expensive art. "Okay, we've got an explosive, but nothing to detonate it with. We need a blasting cap."
"What's that?" Jason asked.
Blakely just frowned at him, but Linda explained, "They're little explosives that set off the chunk of plastic explosive."
