 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 a weakened adult Angel in his possession. 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 babies to have Rory sent to Winter Quay. When the TARDIS arrived nearby, he collapsed from shock. (TV: The Angels Take Manhattan)
