Helga came across the green Opel Blitz again two weeks later, on her afternoon off. It was standing behind the main building, near the tradesmen's entrance. The head orderly, Grabbe, and two assistants were putting a dozen patients into the load area of the truck. They were severe cases, mostly old men and women, not an attractive sight. Gotze, meanwhile, was checking something at the back of the vehicle. He bolted the back door and climbed into the driver's cab. The truck drove off, engine roaring. 'Where are the patients being taken?' Helga asked the head orderly.
'You'll have to ask the boss.' Grabbe jerked his head upwards. Dr Urban was watching the truck from his study window.
She set off on her usual walk through the park, wondering whether to order him to walk barefoot through the snow to fetch her leather gloves this evening. Then she would put the gloves on, very slowly, and he would watch, fascinated. He kept asking her to be really strict with him. She ignored his longing glances at the dog whip on the mantelpiece. and this excited him even more. Instead, she ordered him to spend all evening on his knees in front of her, or humiliated him with a few well-chosen words. She hated this game, but she knew that it gave her power over him. Power that she used to demand privileges for the children. That way they got toys, books to read and painting materials, and the kitchen was told to send desserts and cakes to the children's ward more often. Helga asked for nothing for herself.
In 'normal' moments, he was an interesting conversationalist. It was during one of their discussions that she mentioned the subject of mongolism. 'Take little Karl, for instance. The boy is twelve and very independent. He'd be all right in his parents' care, and that would give us room for a more severe case.'
'Children like him don't belong in a healthy community,' he told her.
The sound of an engine brought her back from her thoughts. It must have been a good half-hour since she'd begun. The green truck was approaching from the depths of the park and driving towards the wall. Curious, she made her way through the undergrowth, and saw the vehicle reversing towards the pit she'd almost stumbled into, two weeks before. Gotze got out in a leisurely fashion, climbed up on the step behind the truck and peered through the peephole. Then he unbolted the door and got back into the cab.
The engine roared, raising the load area. The back doors fell open. Human bodies with mouths wide open and limbs akimbo slid off the sloping floor of the truck into the pit. Helga's cries of horror were drowned by the noise of the engine. The load area was lowered again. Gotze jumped out of the driver's cab, spat on his hands and picked up a shovel. Clods of earth thudded down on the dead men and women. Later, she couldn't remember how she had made it back to the house.
Helga had to watch twice more as the orderlies loaded helpless patients into the green Opel Blitz. By now she knew that the poisonous exhaust gases from the engine were funnelled through a hosepipe straight into the air-tight load area, while Gotze drove his cargo of human beings twitching in their death agonies around the park for half an hour, before tipping them into the mass grave.
'Running like clockwork, sir,' she heard him report on the coach-house telephone after one of these drives. She was overcome by a feeling of impotent rage. She was an accessory to an unspeakable crime, and there was nothing she could do about it. Or was there? Perhaps she could send word to the Fiihrer about this monstrous thing? Only how was she to get a message through to him? And ought she to expose herself anyway? If the perpetrators of this crime found out what she was planning to do, and anything happened to her, it would be the end for Karl too.
One morning just before Christmas she found that she could no longer avoid a decision. She was explaining a simple sum to Karl. Lisa was brushing little Hans's hair. Her other charges were busy painting, getting into a colourful mess with spots of bright paint everywhere. They were all enjoying themselves. Helga felt happy in the bustling activity of this selfcontained little world, and suppressed thoughts of what was going on outside.
Evi, the young student nurse, came hurrying in. Helga had sent her to the storeroom to find some pairs of woolly socks for the children. Evi was in a state of great excitement. The stores manager says we can't have any more new things. The whole children's ward is going to be moved in the New Year.' Everything went round in circles before Helga's eyes. Evi chattered on. 'Do you know where to, Nurse Helga? Hartheim would be nice. They say it's a modern, open asylum for the less serious cases. I expect we'll both be going too.'
Summoning up all her strength of will, Helga managed to appear calm and cheerful. 'I've no idea where to, Evi. We'll find out in due course. You take the children to lunch. There's something I have to do.'
She put on her loden coat. It was wet and cold outside: the snow had melted. She left the building, walking the long way round through the park so as to reach the porter's lodge unseen. Papa Zastrow was sitting by the roaring iron stove with Jule. 'Whatever's the matter, Nurse Helga? You look terrible.'
She ventured everything on a single throw. 'They're going to kill the children.'
The old man nodded. 'In Gotze's gas-powered truck, like the others. They call it "elimination of worthless life", those murderers do. Urban's the worst. He's a member of the Racial Hygiene Research Institute staff. An SS institution "for preserving the purity of the Germanic race".'
'The Fuhrer must be told at once!'
Zastrow's barking laughter turned to a coughing fit. 'The Fiihrer?' he croaked when the coughing had died down. 'Him? He gets his executioners' reports fresh off the press on his desk.'
'He knows about it?'
'He laid the foundations for this madness. You can read all about it in his book — Mein Kampf, it's called. He leaves other people to carry out his plans.'
Helga returned to the immediate problem. 'Papa Zastrow, I have to get away from here, only — only not on my own. Please help us!'
'Us?'
'Karl and me.' Quickly. she filled him in.
Zastrow thought for a moment. 'Do you know the branch of the river that runs outside the little gate?'
' Yes.'
'On Christmas Eve they'll be celebrating.' He gave her a large iron key. 'The spare key. No one knows about it. The lock will be oiled. Slip away around seven that evening. When you're out there, signal with a light. Mato will strike a match to show you where the boat is. He's my youngest. He'll take the two of you to safety.'
Gi tze was being Father Christmas, handing out sugar stars and gingerbread. Some of the children were frightened of his white beard, others were stuffing themselves happily. Candles burned on the wooden Yule pyramid. Dr Urban had installed this piece of pseudo-Germanic folklore in person, before setting off to join his family in Berlin. Helga could have screamed with fury and outrage at the murderer's cynicism.
Nurse Evi had taken little Hans on her lap and was singing, 'Silent Night'. Her young face wore a childlike, devout expression. Karl was looking at her with the awakening interest of puberty.
Helga glanced at the clock. Time to get moving. She sniffed, wrinkled her nose, and drew her son closer to her. 'Oh, Karl, a big boy like you, having an accident!'
Karl protested. 'Didn't dirty my pants!'
'We'll see about that. Evi, we're going to freshen up. It may take a little time.' The student nurse raised her hands and struck up '0 Tannenbaum'.
Helga took her son's arm. The corridor and the stairs were deserted. She heard a babble of voices from below. The staff were celebrating in the hall, along with those inmates who were in any state to do so. In her room she put woollen stockings on her son, socks, a track suit and a thick sweater, as well as gumboots and a woolly hat, items that she had removed one by one from the stores. 'Didn't dirty my pants,' Karl insisted.
