and former household knights, and one such attempt got at least as far as breaking into the prison within the castle. As a result of these threats, Edward was moved around to other locations in secret for a period, before returning to permanent custody at the castle in late summer 1327. The political situation remained unstable, and new plots appear to have been formed to free him. On 23 September Edward III was informed that his father had died at Berkeley Castle during the night of 21 September. Most historians agree that Edward II did die at Berkeley on that date, although there is a minority view that he died much later. His death was, as Mark Ormrod notes, "suspiciously timely", as it simplified Mortimer's political problems considerably, and most historians believe that Edward probably was murdered on the orders of the new regime, although it is impossible to be certain. Several of the individuals suspected of involvement in the death, including Sir Thomas Gurney, Maltravers and , later fled. If Edward died from natural causes, his death may have been hastened by depression following his imprisonment. The rule of Isabella and Mortimer did not last long after the announcement of Edward's death. They made peace with the Scots in the Treaty of Northampton, but this move was highly unpopular. Isabella and Mortimer both amassed and spent great wealth, and criticism of them mounted. Relations between Mortimer and Edward III became strained and in 1330 the king conducted a coup d'état at Nottingham Castle. He arrested Mortimer and then executed him on fourteen charges of treason, including the murder of Edward II. Edward III's government sought to blame Mortimer for all the recent problems, effectively politically rehabilitating Edward II. Edward III spared Isabella, giving her a generous allowance, and she soon returned to public life. Burial and cult Edward's body was embalmed at Berkeley Castle, where it was viewed by local leaders from Bristol and Gloucester. It was then taken to Gloucester Abbey on 21 October, and on 20 December Edward was buried by the high altar, the funeral having probably been delayed to allow Edward III to attend in person. Gloucester was probably chosen because other abbeys had refused or been forbidden to take the king's body, and because it was close to Berkeley. The funeral was a grand affair and cost £351 in total, complete with gilt lions,
