Bourrienne refrained from comment, and waited a moment before coughing lightly. ‘Do you wish me to take down a letter to him, sir?’

‘No . . . Wait.’ Napoleon’s head rose a little higher above the steam swirling off the surface of the water. ‘He’s reviewing a new cavalry formation near Montmartre, is he not?’

‘Yes, sir.’

‘Then send for him. I will meet him here this evening, with Berthier and Talleyrand. See to it at once.’

Bourrienne stood up, collected his papers and bowed, greatly relieved to quit the stifling humidity of Napoleon’s bathroom. As he made for the door there was a splash of water from the overfilled bath as Napoleon raised an arm. ‘And send Roustam in. It’s time I was out of here and got dressed.’

‘Yes, sir.’

Once he was alone again Napoleon raised his hands to his face and relished the sensation of moist warmth against his eyes. He was tired. More tired than he had ever been and more tired than he should permit himself to be, he reflected. In truth, the seemingly endless difficulties facing the government could only begin to be solved if there was peace with England and Austria. But that seemed more unlikely than ever, now that the two powers had curtly rebuffed his offers to talk peace. If only that wretched man William Pitt could put the interests of his people above his personal abhorrence of France there might be peace, Napoleon considered. However, there was little hope of that, and Napoleon resigned himself to the prospect of the English Prime Minister obstinately dragging out the war for years to come, defying France, and Napoleon, from the other side of the Channel. Meanwhile, Austria was the only enemy that France could close with and destroy. So it was against Austria that the full fury of France’s army would be launched.

‘Sir, your gown.’

Napoleon glanced up with a start. Once again his intense preoccupation with policy had driven out all awareness of his surroundings and Roustam had entered the room without his realising. He stared at his Mameluke servant and wondered if this blindness to minions was what happened when a man became a ruler of his nation. If so, it was a dangerous development, and Napoleon had no intention of ending up like Marat. He rose up, shedding water in a steaming cascade, and stepping out of the bath he took the gown that Roustam proffered to him, anxious to get dry and dressed in his uniform so that he would no longer feel naked and vulnerable.

‘Would you like breakfast, sir?’

‘Yes. No, wait. Is my wife still in bed?’

‘I believe so, sir.’

‘Then I’ll have breakfast later.You may go.’
