‘No more than I would the killing of an emperor. Considerably less, in fact. Besides, you are missing the point. By exposing this conspiracy we could demonstrate our good faith to Talleyrand, and, through him, to Napoleon. It would surely help our attempt to open peace negotiations. In any case, the argument is academic. I have already sent a message to Talleyrand to warn him of the plot.’

There was silence in the room as the others took this in and showed their surprise, and some disgust. Grenville was the first to recover and he turned fully towards Fox and glared. ‘You go too far, sir. The dissident’s approach to you should have been reported to me directly. The decision as to whether to back the man, or turn him down, was not yours to make.’

‘It was a foreign policy issue, sir, and therefore well within the responsibilities of my office.’

‘That is enough! You should have discussed this with the Cabinet, or me at the very least. In future, I demand that you report any further such activity to me directly. Understand?’

‘Yes, Prime Minister. I understand.’ Fox smiled faintly, then suddenly reached down and examined his pocket watch in the candlelight. ‘Ah, I’m afraid I must beg your pardon and leave you, gentlemen. I have a prior engagement. I am taking my wife to a late recital.’

‘A recital?’ Grenville gently stroked his frown-streaked brow. ‘Don’t you think this meeting is more important than a recital?’

‘In truth? No. A man who neglects his wife is no man at all, sir. So I must go. Gentlemen.’ Fox stood up and bowed his head to each of the brothers on the opposite side of the table. ‘I will leave you to your politics, then. Good night.’

He clasped his hands together, stretched his back and strode towards the door. ‘I’m sure I will be seeing you all again soon. Especially the Wellesleys, who will have to face some tough questions in the House if I am any judge of my own supporters. Once again, good night, gentlemen.’

Taking his cape and hat from the stand, Fox opened the door and left the room.The others stared after him as the door clicked shut. Richard let out a low dry laugh and was the first to speak.

‘Well, Grenville, it appears that you have your work cut out for you with that man. I should not like to work alongside him.’

‘You can’t begin to imagine . . .’ muttered the Prime Minister. ‘But on one thing he is right.There is no avoiding the need to have him in government. At least it keeps his supporters relatively quiet. It is both a pity and a paradox that Fox is less of a danger inside the Cabinet than without.’
