Peter C. Mitchell is a friend of Dr. Nora Barlow and a member of the Zoological Society of London. In real life, he was Scottish and secretary of the Zoological Society. He is the only character in the books on first name terms with Dr. Barlow.
In the seriesEdit
P. C. Mitchell is mentioned only in Goliath. After Deryn gives Dr. Barlow the rock sample that Nikola Tesla found in Tunguska, Dr. Barlow determines that she cannot properly analyze the sample and sends it off to "someone with intellect." Later, Deryn reads the name "P. C. Mitchell" on the top secret message tube of the bird returning the sample. Mitchell tells Dr. Barlow in his letter that the sample is of natural formation, consisting of iron, nickel, cobalt, phosphorous and sulfur.
