Great-uncle Charlie

That let out the police. I mentally took stock of my only remaining relatives. Aunt Polly, Grandma Phibbs and my great-uncle Charlie. They were all healthy as far as I knew. You could have knocked me over with a feather when I picked up the telephone and heard Rankin's voice.

Charlie is Daniel Gerad’s surviving great-uncle, mentioned among his remaining relatives. No surname is supplied.
