Arthur stared back at him, frowning. There had been a time when William had been principled, priggish even, but now Arthur saw that his brother had succumbed to the base values of those who had made Parliament their home. He felt tired, and unwilling to continue the discussion. If William wanted to play politics Arthur would not dissuade him. But he would not let himself surrender to the same temptation. Even so, however distasteful it might be, Arthur realised that he would have to bend a little in order to serve Britain’s interests. He leaned towards the fire and shovelled some more coals on to the fire.

‘Very well then, William. I will speak to Lord Buckingham.’

William smiled in warm satisfaction. ‘I knew you would see sense. I will broach the matter with him as soon as possible.’

Arthur nodded, and then fixed his brother with a firm look. ‘Mind you, I will not commit myself to his cause.You understand?’

‘I understand. Trust me, you need only talk to the man.’

As the chilly winter days passed and Arthur made his rounds of the social events of the capital he felt as if he was surrounded by enemies, seen and unseen. So it was that when an invitation came from Lord Buckingham to meet him at his grand house at Stowe early in November, Arthur gratefully accepted the chance to escape London for a few days. It would be good to breathe fresh air. Buckingham was known for his love of the hunt and Arthur, who shared the passion, looked forward to the chance to ride again. William let Arthur use his carriage for the journey and, on the morning Arthur left, his brother gently took his arm as he settled into his seat.

‘Remember, this man could be vital to our fortunes. Be careful what you say to him.’

Arthur smiled. ‘Trust me.’
