#also since I'm quoting from her book I just wanted to point out: Nicola Tallis was beyond horrendous towards Elizabeth Woodville

“Throughout Henry’s exile, Margaret (Beaufort) seems to have been a faithful correspondent, keeping her son abreast of affairs in England. Though none of their letters from this period have survived, it is highly probable that they contained sentiments similar to those she expressed in her later letters to him: she often gave him her blessing, and on one occasion, in a reflection of her affection towards him, she assured Henry that ‘I trust you shall well perceive I shall deal towards you as a kind, loving mother’. At this time, however, Margaret was clearly considering the possibility of bringing about his return, though she also recognised that this would take time. As her standing with Edward IV improved, so too did her confidence to effect a reconciliation. If she could continue to win the king’s trust, Henry’s foreign exile could potentially be brought to an end.

By the beginning of June 1482, her efforts appear to have produced some results when Edward agreed that Henry could receive a share of his grandmother the dowager Duchess of Somerset’s lands to the value of £400 (£276,500) if he were to return ‘to be in the grace and favour of the king’s highness’. Edward signed the agreement on 3 June, attaching his official seal. A draft still survives and can be found among Margaret’s papers. The groundwork for Henry to return home had been laid. Edward’s grip on the reins of power was unchallenged, and with two surviving sons, his dynasty appeared to be assured—Margaret’s son was no longer a threat. Thus it was that, on an unknown date, Edward—curiously, using the same piece of paper on which Margaret’s second husband had been created Earl of Richmond—drafted a pardon for her son. Margaret began to hope that she and Henry would soon be reunited.”
