What did Grimwig say Oliver would abscond with?

Mr. Grimwig believed that Oliver would abscond with the five pound note, the books, and the new suit of clothes.

‘No,’ he said, smiting the table with his fist, ‘I do not. The boy has a new suit of clothes on his back, a set of valuable books under his arm, and a five-pound note in his pocket. He’ll join his old friends the thieves, and laugh at you. If ever that boy returns to this house, sir, I’ll eat my head.’
