In John Sandford's "Extreme Prey," the character Palmer is shocked by the revelation of a murder. His reaction reveals a sense of disbelief and intrigue, as the notion of someone being killed provokes a strong response from him. He is portrayed as a somewhat unassuming figure, which adds to the unexpected nature of his surprise.

Palmer is described as a thin man with distinct physical features, including a bald head and a freckled complexion. Dressed in a casual outfit that humorously references the NSA, his appearance contrasts with the seriousness of the murder discussion, highlighting the tension between mundane life and the gravity of the situation unfolding around him.
