Harry Potter and the Half-Blood Prince cassettes 1,2,3,and 4 side A of 12

Harry has just discovered that the Half-Blood Prince wrote the notations in his textbook. I like this one much better than number five. I get the impression she enjoyed writing it more. The scene with the prime minister was particularly well done. Especially the part about how no one would believe him if he told. I also quite enjoyed Hermione's reaction to Harry's success with the potion.
