Varencourt reiterated once again that he was acting on Napoleon’s orders. He then continued, but in French, as though to acknowledge that he felt more at ease in that language.

‘A few days ago His Majesty Joseph I charged me with investigating all the royalist organisations in the capital. I was also meant to be looking for Count Kevlokine, a close associate of your Tsar, in fact his principal agent here in Paris.’

Lyzki started to look concerned. ‘I know Count Kevlokine well. Continue.’

The count has been murdered. And what’s worse, he was tortured. His hands and arms were burnt.’

‘We know that.’

Varencourt had been banking on Alexander knowing this. The Tsar must either have been told about his friend’s death by Russian agents, or by informers at the heart of the French police. Or else he had asked people to find out about it, as soon as he had entered Paris.

‘Well, it so happens that after a complicated investigation I managed to identify the murderer.’

Major Lyzki had now completely abandoned his nonchalant demeanour.

‘What’s his name?’ he demanded.

‘His identity is somewhat problematic. That’s why I can speak only to the Tsar himself.’

‘I don’t understand. You say that you are on a mission for your Emperor, then you speak of an investigation

‘I’m not saying any more! I value my life! Before I reveal anything I want the Tsar’s personal assurance that he will protect me.’

Lyzki was very perplexed. What could the man mean? That Napoleon had ordered the murder and torture of Count Kevlokine? Or that Joseph had? Or did he mean, on the contrary, that it was someone close to Louis XVIII who had given the order, which was why the man was so scared and why Napoleon was demanding that the information be passed to the Tsar?

‘You certainly seem to be in possession of a good deal of knowledge. But there’s one thing I don’t understand, Lieutenant-Colonel Margont. Why are you taking all these risks? What’s your interest in all this?’

‘I value justice above everything else, even my life. It comes from my philanthropy, which is a quality that’s hard to bear, I can assure you. But that’s the way it is. The Revolution changed my life and gave me my love of liberty. And there can be no liberty without justice. It’s hard to explain. I find it difficult to express my determination in words, but I can assure you, it’s relentless. I will carry my investigation through to the bitter end, even if there is nothing in it for me and I lose everything because of it.’

That was the reply Margont had given Varencourt the day he asked him whether he would go on with his investigation if Paris fell to the Allies. Varencourt reproduced Margont’s sentiment almost word for word, trying to use the same gestures and expression. The card he played at that moment had been lifted directly from Margont’s hand ...

Til inform the Tsar of your request,’ announced Lyzki as he left the room, holding Joseph’s letter.

The major led Margont to his colonel, who was to be found in Place Vendome. The square was heaving with soldiers - white-clad Austrians, azure Prussian dragoons banded with white belts, blue Prussian infantry, scarlet Cossacks of the Guard ... A long cord had been attached to the statue of Napoleon dressed as a Roman

emperor, which stood atop the column at the centre of the square, and the infantry of ten countries were pulling and pulling to bring it down. Extraordinarily, the statue held firm on its base, a lone figure amidst a horde of adversaries.

The colonel in charge was most displeased to be interrupted. They were spoiling the spectacle! Instead of answering the major, he spoke to one of his captains.

‘Find an artillery regiment and tell them to put all the gunpowder they can lay their hands on at the foot of the column!’

The captain was aghast. He had no choice but to obey. But they had all been given orders to be respectful to the Parisians and here was his colonel wanting to blow up the Place Vendome. With so much gunpowder that the debris would rain down on the Louvre, the Tuileries, the head of the Tsar...

That column’s made out of our cannons!’ fumed the colonel. The cannons we lost at Austerlitz, which they melted down!’

Then he came to his senses and rescinded his order. What? What now? Someone wanted to kill the Tsar? They should go and discuss that with those in charge of protecting His Imperial Majesty. As Margont was rejoicing at this command, finally feeling that it would be possible to get to Rue de Rivoli, the colonel went off towards the column. He was jolly well going to pull on that cord himself, and make his staff officers do the same.

Varencourt was still in the waiting room. Were they keeping him waiting on purpose? Or was Lyzki afraid to disturb the Tsar while he was in the middle of discussing the future of France and Russia? That was life: you tried to plan what you would be doing in one, two, five or ten years, not knowing that actually you were living your last ten minutes ...

From Place Vendome, Margont and Lefine went down Rue de Castiglione and were stopped by some chasseurs of the Russian Guard at the entrance to Rue de Rivoli. Unfortunately this was not the way Varencourt had come, so these soldiers, who only dealt with their street and paid no attention to the continual comings

and goings on Rue de Rivoli, knew nothing about any Frenchman asking to see the Tsar.

Margont explained as best he could to a captain sporting a bloodstained bandage on his forehead. Several of his men had also been wounded in the taking of Buttes-Chaumont.

‘No one is going to kill the Tsar,’ the captain said decisively, once Margont had finished.

Napoleon had renamed the streets running off Rue de Rivoli after his victories, in a bid to make the area more popular. It was at Castiglione, near Mantoue, that Napoleon had beaten the Austrians under Wurmser. Three Russian chasseurs were engaged in using their bayonets to try to prise off the stone plaque engraved with the name Castiglione, and the captain was more interested in that activity than in the ramblings of this Frenchman.

Lefine was patting Margont on the back with one hand to calm him, whilst with the other he was restraining him by the sleeve. He knew his friend was perfectly capable of trying to storm through the Russian Guard!

Margont changed tactic. ‘Listen, ask Monsieur de Talleyrand to come here. He knows me and will confirm that you should take what I have to say seriously.’

The captain started to lose patience.

Margont added: ‘It was only two days ago that Monsieur de Talleyrand was obeying Napoleon and standing shoulder to shoulder with Joseph. He helped organise the defence of Paris. It’s partly his fault you’re wounded. So it’s fair enough to go and disturb him!’

That seemed to appeal to the captain. He had still not come to terms with the fact that Talleyrand, a dignitary of the Empire, had not been thrown in prison. Far from it - the Prince de Benevent was taking tea with the Tsar!

‘All right,’ he replied. ‘I’ll try. Not for you, for my own personal satisfaction. But if you’re lying to me I’ll have you executed on the spot - your friend too. I have the power to do that. Do you understand me?’

‘I understand.’

In the captain’s mind, disturbing Talleyrand was the equivalent of removing at one stroke all the street signs in Paris commemorating imperial victories. He gave the order to a lieutenant, who immediately ran off. Margont’s Russian was rudimentary. He thought he had grasped what the officer had said but ... no ... he must have misunderstood ... surely ...

‘Could you tell me in French what you just told the lieutenant?’ he asked.

The captain looked disgusted as he said, ‘I told the lieutenant, “Go and find Monsieur de Talleyrand and tell him that he is requested to present himself at our guard post to deal with a matter of extreme gravity concerning the Tsar. A certain Lieutenant-Colonel Margont is asking to see him. Do your utmost to ensure that the head of the Provisional French Government attends in person.’” The head of the Provisional French Government?’ repeated Margont.
