Amelia recognised the letter-writer’s surname. Julie’s father was one of the Aurors at the prison who had been suspected of the Death Eaters’ deaths, had been thoroughly investigated, and had eventually been cleared. Amelia was willing to bet that young Julie had not "heard" the rumour, but had made up the rumour, and was trying to get the "rumour" circulated in order to remove whatever suspicion about her father still lingered.
