Task: Question Answering
Input (English): Passage: According to Max Clifford: Read All About It, written by Clifford and Angela Levin, La Salle invented the story out of frustration with Starr who had been working on a book with McCaffrey. She contacted an acquaintance who worked for The Sun in Manchester. The story reportedly delighted MacKenzie, who was keen to run it, and Max Clifford, who had been Starr's public relations agent. Starr had to be persuaded that the apparent revelation would not damage him; the attention helped to revive his career. In his 2001 autobiography Unwrapped, Starr wrote that the incident was a complete fabrication: "I have never eaten or even nibbled a live hamster, gerbil, guinea pig, mouse, shrew, vole or any other small mammal." Question: Who was writing a book with McCaffrey?
Output (English): Starr
