Napoleon nodded and shut the door. At once the carriage lurched into motion and rattled over the cobbled street as the mounted policemen cleared a path through the crowd, warily looking about them for any sign of further danger to the First Consul.

At his private apartments, Napoleon went immediately to find his wife. She was in her private sitting room, with her son, her physician and some of her closest friends. Her face was streaked with tears as she watched the doctor tend to Hortense’s wound. Napoleon stared at them for a moment, before the doctor noticed him and called out softly, ‘She will be fine, sir. She’s lost a lot of blood, but she is a strong girl.’

Napoleon nodded his gratitude and then quietly slipped away to his study. He felt guilty. The bomb was meant for him, not Josephine’s daughter, and she would not have been injured if he had not become the First Consul, or if he had not decided to arrange the trip to the Opéra. Reaching his study, he ordered a servant to light the fire, and then he poured himself a drink and sat down to wait for Fouché.

Shortly after midnight, the door to the study clicked open and Napoleon glanced up as the Minister of the Interior entered the room. He nodded towards a chair on the other side of the fire and Fouché sat down.

Napoleon cleared his throat. ‘What was the butcher’s bill?’

‘Over fifty casualties so far, half of them dead.’ Fouché paused a moment before he changed the subject. ‘But you’re alive and unhurt, and that’s the main thing. I’ve primed the newpaper editors with the story I want to run tomorrow. I’ve told them it’s the work of royalist and Jacobin agents.’

Napoleon sniffed faintly. ‘An unlikely combination.’

‘Maybe, but this outrage may provide the excuse we need to crack down on both parties. I’ve given orders to start rounding up all those we suspect of being their ringleaders. Someone will know something about the plot. It’s just a matter of asking the questions in the appropriate manner.’

‘You’re talking about torture.’

‘Torture? Not the word to use, I think.We’ll call it something like coercive interrogation, to help keep the newspapers on our side.We might possibly discover who was behind the plot, but we are sure to uncover a great many pieces of useful information while we are at it.’ His eyes glinted at the prospect, before he assumed a more sombre expression and leaned forward towards the First Consul. ‘I heard the news about your stepdaughter a short while ago. I am told she will recover. That must be a comfort to know.’
