The novel ends with Archie confronting Wolfe, having realized that Wolfe staged the cylinder's discovery and in fact knew it was in his office the whole time. He is simply unsure of whether Wolfe waited so long for "art's sake," or simply to ensure that he could collect a $100,000 reward offered by the NIA instead of the $30,000 fee. Wolfe does not disagree with either hypothesis, but suggests another motivation: having come to respect Phoebe Gunther's intelligence and determination, Wolfe decided to continue as far as possible her objective of causing damage to the NIA. In gratitude for saving his career, Inspector Cramer timidly gives Wolfe an orchid for a gift.
