Last night in Azkaban, all eight convicted Death Eaters had been Kissed when someone had used the Snakestone to open all their prison doors. However, all the evidence suggested that the Snakestone had been neither stolen nor copied. Meanwhile, there was simply no way that an outsider could have sneaked into the prison and could have committed the murders, because Azkaban’s fierce wards would not have let this happen. This left only one possible explanation for how the murders had happened: this was an inside job. Yet the warden, the two Aurors who had been on patrol at the time, and the rest of Azkaban’s Aurors, who supposedly all had been asleep at the time, all passed Veritaserum questioning.
