'So a Swiss fire extinguisher.'

'I told you I'm sorry, Bernard. You know I wouldn't have had this happen for the world. I can't blame you for being angry. In your place I would be angry too.' Both his arms were clasped round the cheap briefcase as if it was a baby. I suddenly guessed that it was stuffed with money; money that had come from the exchange of the gold.

At that I gave up. There are some people who won't learn by good advice, only by experience. George Kosinski was that sort of person.

Soon after that a man I recognized as George's driver and handyman arrived. He brought a car rug to wrap around the injured man and lifted him with effortless ease. George watched as if it was his own sick child.

Perhaps it was pain that caused the injured man's eyes to flicker. His lips moved but he didn't speak. Then he was carried down to the car.

'I'm sorry, Bernard,' said George, standing at the door as if trying to be contrite. 'If you have to report it, you have to. I understand. You can't risk your job.'

I cleaned the mat as well as possible, got rid of the worst marks in the bathroom and soaked a bloody towel in cold water before sending it to the laundry. In my usual infantile fashion, I decided to wait and see if Fiona noticed any of the marks. As a way of making an important decision it was about as good as spinning a coin in the air, but Fiona had eyes for little beyond the mountains of work she brought home every evening, so I didn't mention my uninvited visitors to anyone. But my hopes that George and his antics were finished and forgotten did not last beyond the following week, when I returned from a meeting and found a message on my desk summoning me to the presence of my boss Dicky Cruyer, newly appointed European Controller.

I opened the office door. Dicky was standing behind his desk, twisting a white starched handkerchief tight around his wounded fingers, while half a dozen tiny drips of blood patterned the report he had brought back from his meeting.

There was no need for him to explain. I'd been on the top floor and heard the sudden snarling and baritone growls. The only beast permitted through the guarded front entrance of London Central was the Director General's venerable black Labrador, and it only came when accompanied by its master.

'Berne,' said Dicky, indicating the papers freshly arrived in his tray. 'The Berne office again.'

I put on a blank expression. 'Berne?' I said. 'Berne, Switzerland?'

'Don't act the bloody innocent, Bernard. Your brother-in-law fives in Switzerland, doesn't he?' Dicky was trembling. His sanguinary encounter with the Director-General and his canine companion had left him wounded in both body and spirit. It made me wonder what condition the other two were in.

'I've never denied it,' I said.

The door to the adjoining office opened. Jennifer, the youngest, most devoted and attentive of Dicky's female assistants, put her head round the door and said, 'Shall I get antiseptic from the first-aid box, Mr. Cruyer?'

'No,' said Dicky in a stagy whisper over his shoulder, vexed that word of his misfortune had spread so quickly. 'Well?' he said, turning to me again.

I shrugged. 'We all have to live somewhere.'

'Four Stasi agents pass through in seven days? Are you telling me that's just a coincidence?' A pensive pause. 'They went to see your brother-in-law in Zurich.'

'How do you know where they went?'

'They all went to Zurich. It's obvious, isn't it?'

'I don't know what you're implying,' I said. 'If the Stasi want to talk to George Kosinski they don't have to send four men to Zurich; roughnecks that even our penpushers in Berne can recognize. I mean, it's a bit high-profile, isn't it?'

Dicky looked round to see if Jennifer was still standing in the doorway looking worried. She was. 'Very well, then,' he said, sitting down suddenly as if surrendering to his pain. 'Get the antiseptic.' The door closed and, as he tightened the handkerchief round his fingers, he noticed the bloodstains on his papers.

'You should have an anti-tetanus shot,' I advised. 'That dog is full of fleas and mange.'

Dicky said, 'Never mind the dog. Let's keep to the business in hand. Your brother-in-law is in contact with East German intelligence, and I'm going over there to face him with it.'

'When?'

'This weekend. And you are coming with me.'

'I have to finish all that material you gave me yesterday. You said the D-G wanted the report on his desk on Monday.'

Dicky eyed me suspiciously. We both knew that he recklessly used the name of the Director-General when he wanted work done hurriedly or late at night. 'He's changed his mind about the report. He told me to take you to Switzerland with me.'

Now it was possible to see a little deeper into Dicky's state of mind. The questions he had just put to me were questions he'd failed to answer to the D-G's satisfaction. The Director had then told Dicky to take me along with him, and it was that that had dented Dicky's ego. The nip from the dog was extracurricular. 'Because it's your brother-in-law,' he added, lest I began to think myself indispensable.

Using his uninjured hand Dicky picked up his phone and called Fiona, who worked in the next office. 'Fiona, darling,' he said in his jokey drawl. 'Hubby is with me. Could you join us for a moment?'

I went and looked out of the window and tried to forget I had a crackpot brother-in-law in whom Dicky was taking a sudden and unsympathetic interest. Summer had passed; we had winter to endure before it came again but this was a glorious golden day, and from this top-floor room I could see across the London basin to the high ground at Hampstead. The clouds, gauzy and gray like a bundle of discarded bandages, were fixed to the ground by shiny brass pins pretending to be sunbeams.

My wife came in, her face darkened with the stem expression that I'd learned to recognize as one she wore when wrenched away from something that needed uninterrupted concentration. Fiona's work load had become the talk of the top floor. And she handled the political decisions with consummate skill. But I saw in her eyes that bright gleam a light bulb provides just before going ping.

'Yes, Dicky?' she said.

'I'm enticing your hubby away for a brief fling in Zurich, Fiona my dearest. We must leave Sunday morning. Can you endure a weekend without him?'

Fiona looked at me sternly. I winked at her but she didn't react. 'Must he go?' she said.

'Duty calls,' said Dicky.

'What did you do to your hand, Dicky?'

As if in response, Jennifer arrived with antiseptic, cotton wool and a packet of Band-Aids. Dicky held his hand out like some potentate accepting a vow of fidelity. Jennifer crouched and began work on his wound.

'The children were coming home on Sunday,' Fiona told Dicky. 'But if Bernard is going to be on a trip, I'll lock myself away and work on those wretched figures you need for the Minister.'

'Splendid,' said Dicky. 'Ouch, that hurts,' he told Jennifer.

'I'm sorry, Mr. Cruyer.'

To me Fiona said, 'Daddy suggests keeping the children with him a little longer.' Perhaps she saw the quizzical look in my face for, in explanation, she added, 'I phoned them this morning. It's their wedding anniversary.'

'We'll talk about it,' I said.

'I've told Daddy to reserve places for them at the school next term, just in case.' She clasped her hands together as if praying that I would not explode. 'If we lose the deposit, so be it.'

For a moment I was speechless. Her father was doing everything he could to keep my children with him, and I wanted them home with us.

Dicky, feeling left out of this conversation, said, 'Has Daphne been in touch, by any chance?'
