Biography
Mitchell and his security team were called in from London to Fetch Priory after the death of a hiker.

On arrival, he got into an argument with, and offended, Martha Tyler, the cook at Fetch Priory, as she had arrived without clearance — threatening to take her outside and set the guard dog on her.

Mitchell was then promptly told by Martha afterwards, after she was vouched for by Adam Colby and Thea Ransome: "There 'int a dog born that'd go for me, son. They've got more sense than some people!"

While in the priory's kitchen, Mitchell was killed by a Fendahleen. (TV: Image of the Fendahl)
