Steve smiled back Timur, relieved to see him in a friendly frame of mind. “Good evening.”

“What are you doing out here in the middle of the night, my friend?” In the flickering torchlight, Timur glanced at Marcia, then back at Steve.

“Be careful,” Marcia whispered in English. “Kidnapping probably gets the death penalty here. Almost every serious crime does.”

Steve understood her point. They did not want to cause her kidnappers, or anyone else, to die. Already, the team had influenced local people to take many actions they would not have otherwise taken.

“We had a misunderstanding with some of our fellow travelers, but it is settled now. I apologize for the inconvenience to you and your men.”

“We can find these people for you. Perhaps you want them punished.”

“No! No, the problem has ended. I gave them a good scare myself.” Steve glanced at the riders around them, hoping to change the subject. “You must have brought all the sentries out with you.”

Timur chuckled, and so did many of his companions. “No, my friend. Most of the sentries remain on duty. I saw a mysterious light out here a short while ago and woke up a squad of riders to join me in finding it.”

“It was just this.” Steve lifted up the paper lantern.

“I first saw it moving north. By the time we got out here, we heard you returning and took our positions to intercept you.”

“You were very quiet,” said Steve. He figured a compliment couldn’t hurt. “I had no idea you were coming toward us or waiting here.”

Timur simply nodded casually. “We shall escort you back through the gate.” He turned his horse, and his men imitated his movement. The rough circle of men around Steve and Marcia began to ride south at a walk.

Steve exchanged a glance with Marcia, and they kept pace. He felt safe from Marcia’s kidnappers, but he also knew that Timur was not giving them any options. Their host wanted them returned to where they belonged. In any case, they were now safe from Marcia’s kidnappers, even if that group did turn around and come back.

“You’re okay?” Steve asked Marcia quietly in English. He was not asking for information. Instead, he wanted to convey a message to Hunter, who undoubtedly had heard the entire conversation with Timur. He would still be listening, concerned about their condition.

“I’m fine,” she said clearly.

“So am I.” Steve grinned, sure that she understood what he was doing.

Tired after a long day of riding, Steve would not have minded moving faster. His mount was weary, however, and he decided that asking the Mongols for more speed might lead to a full gallop. He definitely had had enough breakneck riding for one night. So he said nothing and simply gazed up at the Great Wall in the moonlight as they returned to it.

Under the watchtower, Timur reined in. As his companion raised the torch high, the other riders also stopped. In the windows of the watchtower, sentries looked out, their silhouettes outlined against the light of their own fire inside the watchtower.

“Open the gate,” Timur shouted in his accented Chinese. “Open for two lost travelers.”

“The gate opens in the morning,” a sentry called back. “Who is there?”

“You know me,” Timur growled angrily. He rose up in his stirrups. “Open this gatenow! ’

The man with the torch held it so that the light fell clearly across Timur’s face. The sentry who had spoken disappeared from sight. Several of the Mongols had already nocked arrows to their bowstrings.

Steve held himself motionless, hoping that no violence would begin. Next to him, Marcia gasped slightly. He saw now just how arrogant and quick to anger the Mongols could be toward the Chinese.

Afterseveral moments, the gate opened with a creak. A single Chinese sentry drew it open, staring at the Mongols fearfully. Timur rode forward, as did the man holding the torch, and stopped right in front of the open gateway.

“Our friends must return to their inn,” Timur said with cold authority. “Tomorrow I may return through this gate to visit with them again. When I do, I will want to hear that all has gone well for them.”

The sentry nodded quickly.

Still looking down at him, Timur waved Steve and Marcia forward.

Steve rode carefully, glancing at Marcia to make sure she was coming with him. They passed without a word through the arched gate. On the other side, Steve turned.

“Thank you, Timur,” he called in Mongol. “Good evening to you all.”

“Farewell!” Timur waved once, then turned his mount and trotted away in the torchlight of his companion. The other Mongols rode after him, and they all vanished quickly into the darkness.

The sentry sighed loudly, letting his shoulders sag, and closed the gate again.

Steve reached into his pouch for a coin. Timur’s warning to the sentry would probably carry a great deal of weight, but a modest token of generosity would not hurt, either. He tossed a coin to the sentry, who fumbled for it with a surprised look and then had to pick it up off the ground. The sentry gave him a nod of thanks.

As the sentry hurried back up inside the watchtower, Steve rode toward the inn. The stable was dark; the hostler had either gone to bed or was hiding. Steve hung up the paper lantern where he had found it.

“Wait a minute,” said Marcia, following him reluctantly. “We can’t go back to the same inn.”

“Hunter, Steve and Marcia here,” Steve said quietly. “Where are you?”

“Here,” said Hunter aloud, stepping out from behind one corner of the inn. He held the reins to his tired mount and Jane’s, as well. “I am relieved to see that you are both well. I continued to receive your transmission, so I knew you were coming back safely.”

“But now what are we going to do?” Marcia asked. “I’m so tired.”

“So are all the horses,” said Steve. “They’re probably ready to drop.”

“The inn is unsafe,” said Hunter. “The people who have now kidnapped three of us may still be able to return tonight.”

“That’s right,” said Marcia.

“Yeah, that makes sense,” said Steve. “So let’s go back to my original idea-use the sphere to follow Wayne and Ishihara back to Khanbaliq.”

“Can we?” Marcia asked hopefully.

“Why not?” Steve said. “We can get a good night’s sleep.”

“I like the sound of that,” said Marcia, smiling weakly. “I’m really cold. And I hurt from all the riding. I’d love to skip the ride back.”

“I do not like the sound of it,” said Hunter firmly. “We must ride.”

“Why?” Steve asked. “If we jump back, we won’t have to worry any more about a bunch of guys who were last seen riding off north of the Great Wall in the dark. And Wayne won’t have an advantage over us after all. Tomorrow morning, we’ll be right back in the search for MC 5.”

“We must return the horses to the city,” said Hunter. “So we must ride them.”

“That’s a two-day advantage for Wayne and Ishihara,” said Steve. “Not to mention that we don’t know where to spend the night.”

“I will protect you now from further harm,” said Hunter. “We will remain together. We will not be surprised or overpowered again.”

“But what if Wayne finds MC 5 during the next couple of days?” Steve demanded.

“We must return the horses,” said Hunter. “They cannot fit in the sphere with us safely.”

“You know we could be throwing away the entire mission,” said Steve urgently.

“Riding back is not ideal,” said Hunter. “Of course I realize this.”

“Look, we all got suckered into coming up here,” said Steve. “The Polos never came this way at all. Wayne and Ishihara have given themselves a free hand.”

“We bought the horses,” said Marcia. “Why can’t we sell them here?”

“Or even give them away,” said Steve.

“We would be leaving a potentially serious change behind that we can prevent,” said Hunter.

“Hold it right there,” said Steve. “How serious can the horses be?”

“We cannot know,” said Hunter. “That fact is the crucial point.”

“Well, then, as you like to say, what is the likelihood? I don’t think it can be very great.”

“I disagree,” said Hunter. “Horses are very important in this time.”

“I think I may regret this,” said Steve, with a sigh. “But would you explain exactly what harm we can do by selling our horses here?”

“If we leave ours here, they may provide transportation or additional income to people in this town who would not otherwise have had them. Conversely, we may at the same time deprive people in Khanbaliq of those advantages. We must return them to where we found them.”

“I was right,” Steve muttered.

“About what?” Marcia asked.

“I do regret asking.”

“Then you accept my argument?” Hunter asked.

“Maybe not,” Steve said slowly. “It just doesn’t make sense to me.”

“It’s only four horses,” said Marcia thoughtfully. She rubbed her folded arms harder.

“Hunter, horsesare important here-but they’re also very common,” said Steve. “They’re everywhere.”

“That’s true,” said Marcia, with sudden enthusiasm. “In a society that uses horses all the time, they actually have somewhat less value than in our society. In our own time, owning a horse is a luxury, either for the very wealthy or for people like Steve, who live in a rural area where it’s affordable. But in neither case is it a necessity.”

“That’s right,” said Steve.

“I agree that the relative value is different in this society than in ours,” said Hunter. “However, within the context of this society, horses are expensive and important to the people who own them or need them.”

“Well, yes,” Marcia said reluctantly.

“You know we’ve proven that the ordinary changes we’ve caused don’t matter,” said Steve. “On previous missions, we bought weapons in Port Royal and abandoned them in Panama. We took fur cloaks and moved weapons in ancient Germany, too. In the Soviet Union, we caused guys in cars to drive around looking for us and use up gas. We’ve already talked about how consuming food and water and air hasn’t changed anything important in our own time. The horses just aren’t much bigger than the changes we’ve already made.”

“Your list of our past changes is correct, but I judge these horses to be more important. Weapons and clothing were undoubtedly moved in large numbers even without us in Morgan’s mission from Jamaica to Panama and in the Battle of Teutoburger Wald. The mechanical resources and fuel used in the Battle of Moscow also far outstripped the consumption we caused. In each of those cases, our influence was subsumed by the larger events. However, in this case, the effect of leaving our horses would stand alone.”
