Fiske Green-Cahill (AKA the Man in Black or the Man in Gray) (from Attleboro, Massachusetts) is the brother of Grace Cahill. An artist, Fiske was last seen leaving his painting studio before his disappearance forty-six years ago.

In the ninth book, he is shortly known as the "Man in Gray", only to reveal his true identity to Amy and Dan Cahill later on. In the last book, he tells Amy and Dan about the Vespers, and later on adopts Amy and Dan. He is a Madrigal. His official card is No. 198 for his true identity, No. 203 for his alter ego Man in Black, and No. 208 for his other identity Man in Gray.
