Hans took the wheel, and they headed for the rue du Bois.

Reims was a substantial country town with a population of more than 100,000, but there were few motor vehicles on the streets. Cars were used only by those on official business: the police, doctors, firemen, and, of course, the Germans. The citizens went about by bicycle or on foot. Petrol was available for deliveries of food and other essential supplies, but many goods were transported by horse-drawn cart. Champagne was the main industry here. Dieter loved champagne in all its forms: the nutty older vintages, the fresh, light, nonvintage cuves, the refined blanc de blancs, the demi-sec dessert varieties, even the playful pink beloved of Paris courtesans.

The rue du Bois was a pleasant tree-lined street on the outskirts of town. Hans pulled up outside a tall house at the end of a row, with a little courtyard to one side. This was the home of Mademoiselle Lemas. Would Dieter be able to break her spirit? Women were more difficult than men. They cried and screamed, but held out longer. He had sometimes failed with a woman, though never with a man. If this one defeated him, his investigation was dead.

"Come if I wave to you," he said to Stephanie as he got out of the car. Weber's Citron drew up behind, but the Gestapo men stayed in the car, as instructed.

Dieter glanced into the courtyard beside the house. There was a garage. Beyond that, he saw a small garden with clipped hedges, rectangular flower beds, and a raked gravel path. The owner had a tidy mind.

Beside the front door was an old-fashioned red-and-yellow rope. He pulled it and heard from inside the metallic ring of a mechanical bell.

The woman who opened the door was about sixty. She had white hair tied up at the back with a tortoiseshell clasp. She wore a blue dress with a pattern of small white flowers. Over it she had a crisp white apron. "Good morning, monsieur," she said politely.

Dieter smiled. She was an irreproachably genteel provincial lady. Already he had thought of a way to torture her. His spirits lifted with hope.

He said, "Good morning... Mademoiselle Lemas?"

She took in his suit, noticed the car at the curb, and perhaps heard the trace of a German accent, and fear came into her eyes. There was a tremor in her voice as she said, "How may I help you?"

"Are you alone, Mademoiselle?" He watched her face carefully.

"Yes," she said. "Quite alone."

She was telling the truth. He was sure. A woman such as this could not lie without betraying herself with her eyes.

He turned and beckoned Stephanie. "My colleague will join us." He was not going to need Weber's men. "I have some questions to ask you."

"Questions? About what?"

"May I come in?"

"Very well."

The front parlor was furnished with dark wood, highly polished. There was a piano under a dust cover and an engraving of Reims cathedral on the wall. The mantelpiece bore a selection of ornaments: a spun-glass swan, a china flower girl, a transparent globe containing a model of the palace at Versailles, and three wooden camels.

Dieter sat on a plush upholstered couch. Stephanie sat beside him, and Mademoiselle Lemas took an upright chair opposite. She was plump, Dieter observed. Not many French people were plump after four years of occupation. Food was her vice.

On a low table was a cigarette box and a heavy lighter. Dieter flipped the lid and saw that the box was full. "Please feel free to smoke," he said.

She looked mildly offended: women of her generation did not use tobacco. "I don't smoke."

"Then who are these for?"

She touched her chin, a sign of dishonesty. "Visitors."

"And what kind of visitors do you get?"

"Friends... neighbors..." She looked uncomfortable.

"And British spies."

"That is absurd."

Dieter gave her his most charming smile. "You are obviously a respectable lady who has become mixed up in criminal activities from misguided motives," he said in a tone of friendly candor. "I'm not going to toy with you, and I hope you will not be so foolish as to lie to me."

"I shall tell you nothing," she said.

Dieter feigned disappointment, but he was pleased to be making such rapid progress. She had already abandoned the pretense that she did not know what he was talking about. That was as good as a confession. "I'm going to ask you some questions," he said. "If you don't answer them, I shall ask you again at Gestapo headquarters."

She gave him a defiant look.

He said. "Where do you meet the British agents?"

She said nothing.

"How do they recognize you?"

Her eyes met his in a steady gaze. She was no longer flustered, but resigned. A brave woman, he thought. She would be a challenge.

"What is the password?"

She did not answer.

"Who do you pass the agents on to? How do you contact the Resistance? Who is in charge of it?"

Silence.

Dieter stood up. "Come with me, please."

"Very well," she said staunchly. "Perhaps you will permit me to put on my hat."

"Of course." He nodded to Stephanie. "Go with Mademoiselle, please. Make sure she does not use the telephone or write anything down." He did not want her to leave any kind of message.

He waited in the hail. When they returned, Mademoiselle Lemas had taken off her apron and wore a light coat and a cloche hat that had gone out of fashion long before the outbreak of war. She carried a sturdy tan leather handbag. As the three of them were heading for the front door, Mademoiselle Lemas said, "Oh! I forgot my key."

"You don't need it," Dieter said.

"The door locks itself," she said. "I need a key to get back in."

Dieter looked her in the eye. "Don't you understand?" he said. "You've been sheltering British terrorists in your house, you have been caught, and you are in the hands of the Gestapo." He shook his head in an expression of sorrow that was not entirely fake. "Whatever happens, Mademoiselle, you're never coming home again."

She realized the full horror of what was happening to her. Her face turned white, and she staggered. She steadied herself by grabbing the edge of a kidney-shaped table. A Chinese vase containing a spray of dried grasses wobbled dangerously but did not fall. Then Mademoiselle Lemas recovered her poise. She straightened up and let go of the table. She gave him that defiant look again, then walked out of her house with her head held high.

Dieter asked Stephanie to take the front passenger seat, while he sat in the back of the car with the prisoner. As Hans drove them to Sainte-Ccile, Dieter made polite conversation. "Were you born in Reims, Mademoiselle?"

"Yes. My father was choirmaster at the cathedral."

A religious background. This was good news for the plan that was forming in Dieter's mind. "Is he retired?"
