About Robert Holmes

Gabriel Knight is a series of point-and-click adventure games created by Jane Jensen and released by Sierra On-Line in the 1990s. The titular character is an author and book store owner in New Orleans who is investigating a strange series of murders when he learns he is descended from a long line of Schattenjäger. After undergoing a spiritual trial, Gabriel becomes the new Schattenjäger, called on to stop those who use supernatural methods to threaten others. To signify this, he wears the Ritter Talisman, a protective medallion. Not having supernatural abilities himself, Gabriel mainly opposes his enemies with cunning and insight after investigation and research. In the first game, he is assisted by Grace Nakimura. In the two sequels, the two act as partners against evil, with Grace being a playable character.
