'General Guisan,' Marler said suddenly.

'So, you are the right man,' the old lady replied. 'Kurt said you would come. You have come.'

'I come with bad news,' Marler said quietly.

'I know.' The old woman put a hand on her heart. 'I felt it here. Kurt, my husband, is dead.'

'I am sorry. He died very quickly.'

'I am Helga Irina,' she went on. 'Many years ago I was Russian. I met Kurt in the cheap bar. We fell in love then. He was clever man. He helps me to escape from Moscow. Terrible life. He takes me out to Finland. Secret route. To Helsinki. Then to West Germany. We come here, his home. We marry. He was the great man. He tell me if he loses his life his friend, the Englishman, comes. I know him if he says General Guisan. This KGB kind of man on floor follows Kurt. One day in a bar Kurt talks to his Swiss friend. This KGB man sees them. When Kurt goes his friend is made drunk by this man. Barman tells Kurt later. In his drink friend tells Kurt has wife, Irina. Me. Must be how torture man found me. The week later, after friend of Kurt is dragged from river, his head smashed.'

'Can I make sure you get home safely?' Tweed suggested. 'You have had a terrible time. I am sorry.' .

'No!' Irina jumped up from the chair quickly, looked at Marler. 'Kurt tells me give the little black book to the Englishman who says General Guisan.'

She staggered as she began to walk. Tweed grasped her arm, helped her to walk. After a few paces her legs moved normally. She went to the wall to one side of the stove, her gnarled right hand reaching up to a section of the wall. Her fingers worked with surprising agility, Tweed noticed, as she slowly eased out a stone which appeared to be firmly embedded in the wall. She seemed to read Tweed's thoughts.

'I was seamstress in Russia. I am seamstress in Basel when Kurt has married me. It gives me good money to live with.'

She had released the oblong stone which Tweed took from her. Behind where the stone had rested was a cavity. Reaching inside, she brought out a small black book with a faded cover. She walked across the room, handed it to Marler. Behind her back Tweed took out his wallet, extracted ten one-thousand-franc Swiss banknotes, put them in his coat pocket.

'Thank you,' said Marler, taking the notebook from her.

'That is what I would never give to the torture man - no matter what he does to me. Kurt says it has important information.'

'I must pay you the fee Kurt earned.'

'No! It is his gift for you.'

Staring at Marler, Tweed jerked his head towards the door. It was a gesture Marler grasped immediately.

'Now I will take you safely home,' Tweed said.

'It is not needed,' Irina protested. 'I know the way.'

'There may be more bad men outside. I will take you home,' insisted Tweed.

'The stove!' Irina turned, walked to it, bent down and turned something. 'Now it goes cool, then out.'

'We'll deal with that,' said Marler.

'Get out of here as soon as you can,' Tweed whispered to Newman. 'If the police arrive that dead body would take some explaining.'

'Will do...'

Irina had picked up her coat which lay in a heap behind the chair she had sat in. Marler presumed the thug had torn that off her, thrown it down before he began his foul work. He waited until Tweed had escorted Irina halfway across the square and then slipped outside. It was his job to shadow them, then keep out of view while he followed Irina to her home - to make sure she arrived there safely.

'You said at one moment your name was Helga Irina,' Tweed began. He was steering her mind into another direction, hoping it would help her to forget the dreadful ordeal she had suffered. 'Irina is Russian,' Tweed went on as they continued walking. 'Helga is German. I do not understand.'

'You are the boss? The Englishman's boss?'

'Yes, I am.'

'Thank you for what you save me from. I did not thank that nice young man who save me. Please give him my love.'

'I will do that.'

'You were asking me about Helga.' She had slipped her arm inside Tweed's, so he knew he had at last established her confidence in,him. 'My mother was Russian,' she explained. 'She met a German prisoner-of-war who escaped from Stalin's gulag. They fell in love and were married secretly by a priest who had an underground church. So I am Irina for my mother, Helga for my father. They worked for the anti-Communist opposition. I was told by a friend they were trapped trying to escape from the meeting in a cellar. Both were shot dead. I was ten years old.'

What h.e.l.lish lives some people have led, Tweed was thinking. They had crossed another deserted silent square and eventually walked into the Rheinsprung, high up and close to the Minster. Irina slipped her arm free of Tweed's and stopped. As she did so he pushed the folded banknotes into the pocket of her coat. She frowned, slid her hand inside the pocket, feeling what he had put there.

'This is a lot of money. Too much. The black book was a gift from Kurt. I leave you here, but I give back the money.'

Tweed moved away from her so she couldn't hand him anything. He spoke briefly before he began to make his way back down the Rheinsprung, knowing it would lead him to the hotel.

'Kurt earned a big fee. He gave us very valuable information. You cannot give back what Kurt earned. Take care...'

Then he was walking carefully down the steep cobbled slope, wary of its icy surface. He knew that Marler would be somewhere close by, the Invisible Man making sure Irina reached her home safely. Arriving at the bottom, pa.s.sing the Alley of the Eleven Thousand Virgins, he stopped as Newman appeared out of nowhere.

'She's on her way home,' Tweed told him. 'Marler is secretly following her to make certain she gets there.'

They were crossing the empty street, stepping over the tramlines, when Nield and Butler appeared, also out of nowhere. Tweed spoke rapidly before they entered the hotel.

'Pete, you did a great job, saving that poor lady from h.e.l.l. Now, all of you, we must keep away from that area.' He took a notebook from his pocket, opened it at a certain page, handed it to Nield. 'Pete, that's the phone number of Beck's temporary headquarters. Could you call him, disguise your voice, give him the address? Tell him he'll find a corpse there. Be brief - so he can't trace where you're calling from.'

Entering the hotel, he met Paula who had just emerged from the lift. She lowered her voice.

'Keith Kent has arrived. He's in your room. He told me the Americans are going berserk.'

22.

Paula unlocked the room door with the key Tweed had left with her. He had asked her to stay behind in case Kent arrived during his absence. They all followed her inside, with the exception of Nield, who said he was going to his room to make a phone call.

Keith Kent was sitting in an armchair. In his hand he nursed a gla.s.s of brandy. Introductions were not necessary. They all knew the visitor. Kent lifted his gla.s.s.

'With the compliments of Paula. Central heating to warm me up. At least, that's my excuse.'

'I hear you have news,' Tweed said, taking off his coat while the others did the same. Paula took them to hang them up. 'I'd like to hear it,' he said, occupying an armchair close to Kent.

'And I expect you'd all like some hot coffee,' said Paula as she picked up the phone without waiting for a reaction.

Keith Kent was the soul of relaxation. No matter how tense a situation might be, he never showed any sign of nerves. As usual, he was smartly dressed, clad in a dark blue suit, pale blue shirt and a Chanel tie with a motif of peac.o.c.ks.

'I expect Paula has told you,' he began, 'that the Americans are in an uproar. Behaving as though they don't know what to do next. And don't like it.'

'How do you know all this, Keith?'

'This morning I called in at the Zurcher Kredit Bank again - to check that my transaction with the fortune in dollars had been completed. Turned out I didn't even have to speak to the teller. She was occupied - in a big way. A couple of Americans, one of them banging his ugly fist on the counter and shouting at her.'.

'Could you describe him?'

'Not very tall. He has a very big head, clean-shaven, with a boxer's face - slit mouth, tough jaw. Very wide across the chest, tapers down to small feet. Hair brown. He glanced at me once - eyes hard as diamonds.'

'Jake Ronstadt,' Paula said to herself.

'Would he recognize you?' Tweed asked.

'Doubtful. I wore a scarf pulled up over my chin, a hat with the brim pulled down. Normal wear, considering the weather.'

'Go on.'

'As I said, he was shouting at the girl. "There was a fortune in this account and now you show me a balance sheet with zero funds." Then he lowered his voice but I have acute hearing, as you know. He went on raving. "I want to see a friggin' director. I want to see him now. Got it?" That was when he started crashing his fist down on the counter. What the girl said next didn't help.'

'What did she say?'

'That there wasn't a director on the premises. They were away, holding an executive meeting. He really blew his top at that. "Get on that friggin' phone and tell a director to get back here before I bust this place to pieces. Millions and millions of dollars can't vanish, you stupid twit." That was when I quietly left the bank.'

'You said there were a couple of Americans. Can you describe the other one?'

'A tall thin man with a hard thin bony face. I heard the short one call him Vernon.'

'Sounds like that could be Vernon Kolkowski,' Newman interjected. 'I was shown photos of various thugs when I was in New York. The police captain said he was called the Thin Man, a notorious killer. They could never get him. If there were witnesses willing to testify they ended up floating down the Hudson River.'

'Sounds like a suitable candidate for the people we are up against,' Tweed commented.

'After I left the bank,' Kent went on, 'I sat in my parked car to see if anything else happened. It did. About five minutes later the short man with the big chest stormed out of the bank. He walked straight across the street. A car had to come to an emergency stop to avoid running him down. The American crashed his fist down on the car's bonnet, swore foully at the driver and went on to his car. Vernon followed more slowly, as though he didn't want to be too close to the other one. He had to dive into the car as it started moving off.'

'Paula told me the Americans had gone berserk. Probably your word.'

'It does mean,' Kent pointed out, 'that my conjuring trick has worked. Their millions have disappeared into thin air. Could take them weeks, even months, to trace them.'

'Thanks, Keith. You've really achieved something. Don't forget to send me a bill.'

'Oh, I'll bill you.' Keith finished off his brandy and grinned. 'Should I hang around a bit longer?'

'Yes. Where are you staying?'

'At the Hilton.'

'That's fortunate. The thugs are at the Euler, more at another hotel, the Victoria.'

'I'll show you out,' said Paula as Kent stood up. She fetched his coat. 'Yes, I'm coming down in the lift with you.'

'Let's keep in touch,' said Tweed. 'And thanks again...'

Less than a minute after they had left Nield arrived. He accepted Tweed's offer of coffee, settled himself on a couch next to Newman.

'I waited until Kent had left. I made the call a while ago. I had to slam down the phone when Beck tried to ask me questions. He was trying to keep me on the line while he had a trace put out.'

'You kept it brief, then,' Tweed said.

'Simply asked him to take down an address as soon as he came on the line. Then told him he'd find a body there. I had a silk handkerchief over the mouthpiece. Then Beck started to ask me something. I slammed the phone down. Couldn't have been on the line more than thirty seconds.'

'Good.' Tweed looked up as Paula let Marler into the room. 'I trust Irina got home safely'- and without your being seen?'

'Of course she did.' Marler went across to a wall, leant against it. 'And of course she didn't see me.'

'What was that General Guisan business? I gathered it was a pa.s.sword.'

'Exactly that. Kurt once told me that if he went down and later I could get here, I should meet someone in that room. He said if I used "General Guisan" I'd get some valuable information.'

'General Guisan,' Tweed mused. 'The C-in-C of the Swiss armed forces during World War Two. He stopped the n.a.z.is from invading Switzerland by clever threats.' He stopped speaking as the phone rang. Paula answered it. She put it down quickly.

'Beck is here. On his way up.'

Tweed braced himself for an aggressive Beck. Instead, the Swiss police chief came into the room with a quizzical expression. He accepted Tweed's offer to sit down, refused his offer of coffee. He gazed round at them all, one by one.

'All present and correct. I think that's the English phrase.'

'It is,' Tweed agreed.

'In case it's news,' Beck continued, his tone ironic, 'four corpses were found in a street near Market-platz early this morning. All Americans. All with diplomatic pa.s.sports. All blown to kingdom come by a grenade.'

'Disturbing,' said Tweed.

'So, well before dawn, I phoned the Euler. The night receptionist knows me, recognized my voice. I asked him to read out a list of Americans staying there. Recent arrivals. Only one had a suite. I guessed he was the top man. A Jake Ronstadt.'

'We met the gentleman briefly in London.'

'So,' Beck went on, 'I asked to be put through to him.

He was not happy at being woken at that hour. He was even less happy when I gave him the news, read out the names of the deceased. He admitted they were members of his staff, as he put it. Had to. They were registered as staying there.'

'What was his exact reaction, Arthur?'

'Thunderous! Had I caught the villains who committed this foul crime? I hadn't? Why not? He was reporting this to the American Emba.s.sy in Berne. I told him it would take time, that I had only just begun the investigation. He swore at me. I asked him what their profession was.'

'That must have foxed him,' Tweed commented.

'It didn't. He repeated he was getting in touch with Berne. I said I thought that was his best move. He slammed the phone down on me.'

'He. sounds to have been disconcerted.'
