Harry Searches for a Way to Persuade Slughorn

PAGES: 447-448

Harry spends a week wracking his brain to find a way to persuade Horace Slughorn to give him the true memory about Lord Voldemort. With no solution in sight, Harry resorts to studying his Potions book, hoping the Half-Blood Prince has written something useful in the margins. Hermione disapproves of Harry's reliance on the book, reminding him that the Prince might not be able to help with everything.
