unethical practices of the Bureau, she has mailed 10,000 copies of it to prominent figures across the country. Having endured several incidents of harassment and prying, she offers to hire Wolfe to persuade the FBI to leave her alone. Although initially hesitant of making a powerful enemy, Wolfe is persuaded over Archie’s objections when Bruner offers a $50,000 retainer and then doubles it to $100,000, as well as a fee and any expenses he may incur. He is also sympathetic to both Bruner’s plight and the arguments made in the book, and decides not to withdraw in the face of what he sees as heavy-handed and bullying opposition tactics. As the FBI put Wolfe and Archie under surveillance, Wolfe plans to gain examples of FBI malfeasance and use it to persuade the FBI to back down.

Wolfe instead decides that it would serve his purposes better to prove that the FBI had no part in the murder. He also devises a plan to trap the FBI.

Archie discovers that Sarah Dacos, Bruner’s secretary, lives in the same apartment building as Althaus and claimed to have seen FBI agents leaving the apartment on the night of the murder.
