When Henry was finally told of Somerset’s death the shock sent him into such a state of grief that he would not have been capable of ruling anyway. I wondered how Marguerite had taken the news when she heard it, far away in the Lancastrian castle-in-the-lake that was Kenilworth. She must have been distraught that she had lost both her favourite counsellors; Somerset to Warwick’s sword and Wiltshire to self-inflicted exile in Flanders, where he had chosen to take refuge rather than face York’s vengeance. The royal standard had been found propped up against a hovel in a dark alley and most of Wiltshire’s armour was dragged out of the River Ver, which ran through the town. Some monk claimed that the fleeing earl had given him a mark for his habit to use as a disguise.

As for me, the duke chose not to take offence that I had fought against him at St Albans. ‘You are the king’s brother,’ he said. ‘I hold family loyalty in high esteem.’ He went so far as to call me back to the Royal Council, even though I warned him that my prolonged absence from Pembroke would leave crown property in West Wales vulnerable to Gruffydd and his sons. This was where York’s ulterior motive showed, for his response was to favour my brother Edmund, who had not been at St Albans, and appoint him as the king’s Lieutenant in South Wales, with orders to bring Gruffydd to heel. Shuddering at the prospect of Edmund destroying all the diplomatic advances I had made with the ‘old rascal’ and his sons, I went to Henry to protest but it was immediately clear to me that my royal brother was still reeling from Somerset’s death.

With his household scattered he had been accommodated at the Bishop of London’s palace and I found him pale and timid, barely clinging to sanity. ‘Edmund’s appointment was the Duke of York’s idea, Jasper,’ he whispered. There was still a fresh scar on his neck where the arrow had so nearly severed a vital blood vessel. ‘He is very angry about our royal dignity being disparaged in Wales. I thought it best not to argue with him.’

In making my response I swapped my usual cheerful tone for what I hoped was a gently persuasive one. ‘I understand completely, my liege, but on this occasion I believe second thoughts are needed. Highly as I know you regard Edmund, I submit that he is not the man for this task. He makes no secret of the fact that he does not like the Welsh, which must seriously affect the chances of successful negotiations with the local chieftains.’

Henry frowned. ‘But he is Welsh himself and the appointment has been made public. It cannot be changed.’
