Julius Grayle

Mr. Grayle was a collector of Weeping Angels and other artefacts in New York City.

Biography
In 1938, Grayle had baby Weeping Angels locked away in a cellar and an adult Angel chained in his office. He had the latter tortured to see if it could feel pain. He had River Song tightly held in the grasp of the adult Angel, which could only be escaped from by her breaking her wrist. He also used the baby Angels to have Rory Williams sent to Winter Quay.

When the TARDIS arrived nearby, Grayle collapsed from shock and his defenceless mansion was invaded by a duo of Angels. (TV: The Angels Take Manhattan)
