"It was the winter between ’79 and ’80 when things started to change. The Dark Lord borrowed Regulus’ house-elf for something. I do not know why, neither did Regulus, but when it came back, the elf was half-dead. Regulus grew worried, then angry, and then he was surprisingly calm about it. It was a couple of days before Yule, one cold, wet night, when Regulus approached me. He told me that he had discovered the Dark Lord’s secret, and we could soon leave.
