From the Story

Harry Potter and the Half-Blood Prince

Discovered in chapter 15, The Unbreakable Vow

Eldred attends Professor Slughorn's party with his friend Sanguini, a vampire. He shakes Harry's hand enthusiastically when introduced, delighted to meet the boy. He is curious about why there has been no biography of the Boy Who Lived as yet, and mentions that he would be delighted to write one, certain that the book could be finished in months after a few four- or five-hour interviews with Harry.
