Brian Zeller is the head of the Scientific Analysis Section of the FBI. Chief Brian Zeller was young for his job, but already his hair was thinning and he wore bifocals. On the shelf behind Zeller's desk Graham saw H. J. Walls's forensic science text, Tedeschi's great Forensic Medicine in three volumes, and an antique edition of Hopkins' The Wreck of the Deutschland."
Zeller is highly professional and takes his job very seriously, and can be insulted if people imply he is anything be professional. When discussing a report he wrote with Will Graham, he asks was there something incomplete about the report: "Zeller mouthed the word as if it had an unpleasant taste".
He has respect for field agents and the job they do: "Zeller believed that all field men retain the superstitions of the hunt. He was glad to humor Graham."
When Zeller is in a hurry his gabardine pants make a whistling sound that is well known to his staff.
