I am not an impartial observer. Not only am I committed and involved; there is also the basic fact that cops and private detectives are enemies and always will be. Back of the New York cop are the power and authority of eight million people; back of the private detective is nothing but the right to life, liberty, and the pursuit of happiness, and while that’s a fine thing to have it doesn’t win arguments. But though I am not impartial I’m an observer, and one of the privileges of my job is to be present when Cramer walks into the office and aims his sharp gray eyes at Wolfe, and Wolfe, his head cocked a little to the side, meets them. Who will land the first blow, and will it be a jab, a hook, or a swing' On this occasion I got cheated. That first quick impact didn’t take place because Mrs. Yeager didn’t let it. As Cramer crossed the sill into the office she was there confronting him, demanding, “Am I being followed around?” Cramer looked down at her.
