Russell started running. The station side seemed to stretch forever, and he had a painful stitch in his side by the time he reached its end. Turning into Frucht-Strasse, which ran eastwards under the tracks, he saw the car. It was parked on the far corner, in - as Russell ruefully realized - the very next place that Drehsen would have tried if his usual spot had been occupied.
He was out of time, and a train was steaming into the station above him, thundering over the bridge. As he reached the car a couple of girls, prostitutes probably, walked across the end of the street, the click of their heels amplified by the iron ceiling. He stopped for a second, as if searching his pockets for cigarettes, and caught sight of a man with a moustache and slicked-back hair in the black window of a defunct shop. It was himself.
The girls gone, he took another look round, crouched down, and stabbed the driver's side front tyre with the awl Effi had purchased that morning. There was a commendably violent hiss, and the tyre began deflating. From his other pocket he drew a small package of newspaper, gingerly removed the sharp piece of bottle glass it contained, and placed it just behind the wounded tyre. The temptation to disable the spare tyre as well, and make absolutely sure, was almost overwhelming, but he knew that would look too suspicious.
He ran down the southern side of the station, paused outside the entrance to regain his breath, and slipped back into the covered concourse through the stream of exiting passengers. Drehsen was standing in the same spot, his eyes now fixed on Effi . She was standing beside her suitcase some thirty metres away, a few paces from the bottom of the steps, anxiously scanning the concourse for her imaginary welcomer. She looked both lost and slightly angry, as if she was about to burst into tears.
Drehsen moved towards her almost apologetically, a hawk turning into a friendly owl. As she caught sight of him a hint of hope crossed Effi's face.
He let her speak first, and knowing what she intended to say, Russell had no trouble reading her lips: 'Have you come from my uncle?'
Drehsen smiled like an uncle's friend would, said a few words, and reached, almost tentatively for the suitcase. She hesitated for a second, then smiled gratefully back. He gestured towards the exit.
Russell followed them out. As they headed down the side of the station towards Frucht-Strasse he crossed the busy road beyond the taxi rank and headed along the opposite pavement, looking for any sort of concealed vantage point. He found one of the ubiquitous Der Sturmer display cabinets standing almost opposite Frucht-Strasse, and stood there pretending to enjoy the usual cartoons about Jewish bakers draining the blood from Christian children to make their matzoh.
Drehsen and Effi had reached the Mercedes, which she seemed to be admiring. He had opened the back door but Effi , as they had agreed, was insisting on sitting up front. Drehsen shrugged, put the suitcase on the back seat, and opened the front door for her. She got in.
He walked round to the driver's side and was reaching for the door handle when he saw the flat tyre. He got down on his haunches, picked up and examined the piece of glass, and dropped it again. He squatted there for a moment, presumably considering his options. Would he go for the spare?
He opened the driver's door and leaned in, talking to Effi . Was he suggesting a taxi? If not, then she would be. The exchange seemed to last a long time, but eventually he straightened his back, closed the door and went to retrieve the suitcase from the back seat. Effi got back out, and Russell found himself sighing with relief.
She and Drehsen walked back towards the taxi rank in the station fore-court, Russell keeping pace on the opposite pavement. The queue for taxis had evaporated and three were waiting in line. The driver of the leading cab took the suitcase from Drehsen and opened the rear door for Effi . Drehsen said something to him and got in on the other side.
Russell was around thirty metres ahead, close to the western throat of the forecourt. As the taxi pulled out he rushed diagonally across the road towards it, waving frantically. The driver slammed on his brakes, swerved to the right and ground to a halt inches from the kerb.
Effi erupted from the taxi. 'Uncle Fritz!' she cried happily.
'Magda,' he said. 'I'm so sorry. I was held up.'
She explained the situation to the driver, and apologised profusely for losing him his spot at the head of the line. Drehsen climbed slowly out of the back, seemingly unsure what to do, and exchanged glances with Russell. Making up his mind, he touched his cap to Effi and walked back into the station without another word.
It was what they had expected - after all, what else could he do? - but the coolness with which he did it was breathtaking.
Russell took the suitcase and they began walking the short distance to Bre-slauer Strasse, where he had left the Hanomag. Putting an arm round Effi's shoulder, he realized she was shaking. He stopped, put the suitcase down and enfolded her in a hug. She took a huge deep breath.
'All right?' he asked after a while.
'Yes,' she said. 'What a creepy man. And so convincing...'
'Did it work?' Russell interrupted her.
'Oh yes, it did. He told the cabbie Eisenacher Strasse and my heart sank, but the cabbie - God bless him - asked what number. It's 403. We were lucky really. If it hadn't been such a long street he'd never have asked.'
'You did wonderfully.'
'You too.' She reached up to kiss him. 'But the sooner we can dispense with the moustache, the better.'
'First things first,' he said, picking up the suitcase. 'We can take a look at 403 Eisenacher Strasse while Drehsen's getting his tyre changed.'
'He wanted me to wait while he changed it. And he didn't like the idea of a taxi. I had to get quite hysterical before he agreed.'
Eisenacher Strasse ran north to south across Schoneberg for almost two kilometres. Number 403 was a third of the way down, one of a row of detached three-storey houses immediately above Barbarossaplatz. It was impossible to tell which house it was - the sun had set and all were silhouetted against a deep red sky. On the other side of the road, bathed in reddish light, were a typing college and a small bookbinding factory. This part of Schoneberg had seen better days, but it still represented a considerable step up from Neukolln or Wedding. There were no tram-tracks, and not much traffic, but several modest-looking cars were parked in the spaces between the detached houses.
There was no way of stopping without drawing attention to themselves. Russell drove on to Barbarossa Platz, took the third exit, and pulled the car to a halt. 'Let's take a walk,' he said.
Three right turns brought them back onto Eisenacher Strasse, some two hundred metres above the row of houses. There were several other pedestrians on the pavement, and they fell in some twenty metres behind a uniformed young man and his girlfriend. The pair walked ever so slowly, as if intent on stretching out their time together.
The college and factory were in darkness but most of the houses had one or two lighted windows, some curtained, some not. 403 was the third from the end. Every window was curtained, and all showed lines of light. In the parking space alongside, two vehicles were drawn up, and there were two uniformed men talking in the front seats of the one nearer to the road. As they walked past one looked up, caught Russell's eye, and seemed to move them on with an almost involuntary twitch of the head.
'How,' Effi asked, when they'd walked another few paces, 'are we going to find out what's inside?'
'God knows.'
'One more look,' Effi suggested, as they reached the Hanomag.
