AUTHOR
A note in Butler's handwriting announced, COOLER FINE.
'Repaired at last,' thought Artemis as he helped himself to caviar. Then he considered the caviar. There was no denying the Fowls' expensive tastes made a considerable dent in the family fortunes. Artemis needed to make money but, in deference to his father, legitimately; a shame - illegal was always faster. But how? Then it came to him – children's literature! J K Rowling had made millions. He'd publish his fairy adventures under a pseudonym. What should it be?
He glanced at Butler's note: a little mental manipulation and - he had it.
A/N The note Butler left provides Artemis's pseudonym. (Crossword fans should be able to work out what it is.)
