The street remained empty, the darkness occasionally breached by the distant flash of anti-aircraft batteries. Wilhelm's friends reappeared with another dark-haired girl. This one looked about fifteen. She clung to Erich with one hand, and held the neckline of her nightdress up against her throat with the other. 'This is Rachel,' Max said. 'We can't find anyone else.'
'The man said four,' Russell reminded him. He was damned if he was going to come this far and not find Miriam.
'Let me ask Ursel and Inge,' Effi said, and hurried across to the two girls on their stretchers. She returned a few moments later. Miriam's room was on the second floor, at the back.
'I'll go,' Russell told Wilhelm, and headed up the steps.
Inside, the doors were all hanging open. There was a big bed in Miriam's room, but no sign of the girl herself. Russell was looking under the bed when he heard the faintest of whimpers.
She was cowering in a cupboard, knees pulled up against her chin. 'Miriam,' he said, touching her shoulder as gently as he could, and she jerked back as if he'd given her an electric shock. 'Miriam, I'm here to take you away from this place. I've come from your mother and father. From Wartha. They're worried about you.'
She lifted her head and examined his face with a small child's eyes.
'Come,' Russell said gently. 'We must go.'
She wouldn't allow him to help her out of the cupboard, pushing his hand away with a sharp intake of breath. She extricated herself and stood looking at him, dressed in a long white nightgown which accentuated her black hair and olive skin.
He took a robe, and handed it to her. 'You'll need this outside.'
She put it on, and looked at him again, as if awaiting another instruction.
'Let's go downstairs,' he said, and, after only a slight hesitation, she accepted his invitation to walk down ahead of him. Outside she shied away from Wilhelm's helpful arm, but meekly laid down on one of the remaining stretchers.
'It's Miriam, isn't it?' Effi said, squatting down beside her.
The girl just looked up at her.
'Let's get Sternkopf out of the ambulance,' Russell said, but the sudden sound of an approaching vehicle stopped him in his tracks. Two thin head-lights were coming towards them. 'Keep going,' he murmured, but the vehicle was slowing down. As it inched past the ambulance and turned into 403's parking space Russell caught an unwelcome glimpse of silver runes on a black collar.
The car door slammed, and a bright torchbeam leapt out of the darkness, illuminating the pavement in front of the house. 'What is this?' a voice asked.
Russell turned his weaker beam on the intruder. 'This is an ARP exercise and your torch should be masked,' he said sharply, noticing, with a sinking heart, the uniform of a Waffen SS Standartenfuhrer, the holstered gun. He turned to the others. 'Let's get the wounded in the ambulance.'
'Not that one,' the Standartenfuhrer said. He was shining his torch at the fifteen-year-old. 'Rachel and I have a date.'
'You must postpone it,' Russell insisted. 'We can't leave her behind.'
'You can and you will,' the Standartenfuhrer told him, his tone hardening. 'This time tomorrow I shall be with my unit, and I have no intention of letting an imaginary air raid spoil a very real pleasure.'
Several options flicked across Russell's mind, none of them good. Should he, could he, leave Rachel behind to save the others?
A decision proved unnecessary. There was a sudden shift in the darkness behind the Standartenfuhrer, a glint of metal. The man's head jerked forward and his legs gave way, pitching him onto the pavement. Wilhelm had hit him with what looked like an ancient Luger.
'I couldn't see any alternative,' he said almost apologetically, and gave the prone body an exploratory kick in the ribs. 'He'll be out for a while.'
'Let's put him on a stretcher,' Russell heard a voice say. His own.
'No need for fake blood,' Wilhelm said cheerfully, as they carried him across.
He was right - the back of the man's skull was bleeding most convincingly. 'Sternkopf next,' Russell decided. As they carried the caretaker back to the pavement he gave no sign of having overheard the confrontation, but he did recognize the body on the stretcher.
'Standartenfuhrer Geisler,' Sternkopf muttered to himself. 'Another serious head wound,' he added, reading the placard which someone had already put round the unconscious SS officer's neck.
'The Standartenfuhrer is taking the exercise seriously,' Russell told Sternkopf reprovingly.
The rescued girls were sitting in the back of the ambulance, each wearing a placard describing a slight injury. Freya and Effi got in with them, leaving Wilhelm alone in the front. Erich and Max were waiting for Russell in the lorry cab.
'We'll be back in twenty minutes,' Russell told Sternkopf, and clambered up into the cab.
'Why can't you take us on the lorry?' the man complained.
'Health regulations,' Russell said glibly, and started the engine. Since they were supposedly headed for a hospital, they had included one in their itinerary. If they were stopped before they reached the Elisabeth on Lutzow-Strasse, they had their explanation ready. If they were stopped between the hospital and the Landwehrkanal, they would claim they'd got lost in the dark.
No one stopped them. Fifteen minutes after leaving the house on Eisenacher Strasse the two vehicles pulled up alongside the wall separating Schoneberger Ufer from the dark waters of the Landwehrkanal. As Effi swapped vehicles with Max and Erich, Russell handed Beiersdorfer's helmet over to Wilhelm. 'See you tomorrow,' he said.
The ambulance drove off, leaving Russell and Effi alone. 'Miriam didn't say a word,' she said, her voice sounding harsh in the darkness.
Russell drove north through the deserted Tiergarten and across the Moltke Bridge. Beyond the blue-lit Lehrter Station the streets seemed darker still, and he was past the entrance to Hunder's garage before he realized it. He backed up and drove in through the open gates.
Ten minutes later the lorry was back in its corner, complete with its original number-plates. Russell and Effi sat in the front seats of the Hanomag, helping each other remove their make-up by torchlight. 'We're back,' Effi said when they were finally done, and leaned over to kiss him. 'We did it,' she added, sounding almost surprised. 'We really did.'
'We're not home yet,' Russell reminded her.
As they headed south the sirens began sounding the all-clear, but it seemed as if Berlin had already written the night off and gone to sleep. Russell stopped the car halfway across the Moltke Bridge, checked that nothing was coming, and dropped the two Adlon number plates, the false moustache and Beiersdorfer's armband into the Spree. He hoped Wilhelm was being equally thorough.
It felt good to reach home, but the feeling was short-lived. As they came in through Effi's front door the telephone began to ring. They looked at each other, wondering who it could be. 'Did you give Wilhelm this number?' Effi asked.
'No.'
Effi picked up, listened, and said 'Yes, he is.'
'Someone named Sarah,' she told Russell.
He took the receiver. 'Sarah?'
There was a gulping noise at the other end. 'I have to see you,' she said.
'Okay, but...'
'And it has to be now.'
'Ah. All right. I'll walk over.'
'No, no. You must bring the car. Park it round the back. There's an alley runs up from the river end. I'll be waiting.'
Russell replaced the receiver and told Effi he had to go out again.
'What's happened?'
'Trouble,' he told her. 'She didn't explain.'
'You have to go?' It wasn't really a question.
