All the women in the work brigade were well bundled against the cold. Jane could not remember if Judy had told her how long they had been doing this. No snow lay on the ground right now, but Jane could tell by the way the truck bounced and rumbled on the unpaved road that the mud was frozen solid. At one point, she overheard a woman say that the temperature was about minus twenty centigrade.

Finally Jane saw the ditches appear in the distance. As the convoy turned to run parallel to them, heading for the ends still under construction, Jane looked down at them. She estimated that the nearest ditches were about eight meters wide and three or four meters deep.

When the truck creaked to a halt, Jane jumped to the ground with the others and accepted a shovel from someone. No one told her what to do, so she followed the other women. They walked down an earthen ramp into the middle of the ditch.

Some women stood in the center of the ditch, digging the deepest groove. They moved dirt to an intermediate ledge, where other women shoveled it up to the surface. There, a few more women began arranging the dirt into a ridge on each side of the ditch to make the ditch seem even deeper.

Relatively few men were in the brigade. The ones Jane could see were either too old for the military or else injured in some way. The men took picks to the undisturbed, frozen ground at each end of the ditch and began to break it loose.

Jane could see that the purpose of the brigade was to create a ditch big enough and steep enough that German tanks would go front-down into them so sharply that they could not roll forward to come up the other side. Jane picked out a spot a short distance from the other women and switched on her lapel pin. That way, at least, she would hear Hunter in the unlikely event that he called her, despite their agreement that he should not risk it. Right now, it was her best hope. Then she started to dig. If nothing else, the activity helped her keep warm.

Hunter chose to return at midday following the night he left. As before, he took his team to a spot outside the city to avoid being noticed on their arrival. They landed east of Moscow, on the opposite side of the city from the front. He hoped that would help them avoid army patrols from either side.

“You going to call Jane?” Steve asked. “I’m worried about her.”

“I do not dare, at least until taking the risk becomes justified,” said Hunter. “I am not receiving any sound from her, which means she has either turned off her lapel pin or else she is out of range. I calculate the chance of her being surrounded by other people to be extremely high. Jf her lapel pin is turned off or out of range, calling her will not matter. If it is turned on and within range, I would risk attracting attention.”

“Wait a minute,” said Steve. “She’s been through this long enough to know how it works. If it’s turned on, that means she figures it’s safe to hear from you.”

“At this time I will not take the risk,” said Hunter. “We must walk back to the warehouse and see if she is there.” He pointed toward the city.

“Look that way,” said Judy, pointing north as they began to walk.

Hunter saw a faint, dark line on the horizon, too vague to identify. “Do you know what that is?”

“The Sixteenth and Twentieth Soviet armies are encamped that direction,” said Judy. “They’ll be opening the counterattack soon, to drive the Germans back from Moscow. I think we’re looking at the very southern end of their line.”

“Can they help us in any way?” Hunter asked.

Judy shook her head emphatically. “No. The military has political commissars all through it.”

“They are as unpredictable as the NKVD?”

“Well…let’s just say that the potential exists all through the Soviet system. We should avoid all the authorities as much as possible.”
