"Gabriel Knight is a series of adventure games produced by Sierra On-Line in the 1990s. Three games were released in the series: Gabriel Knight: Sins of the Fathers, The Beast Within: A Gabriel Knight Mystery and Gabriel Knight 3: Blood of the Sacred, Blood of the Damned.
The first game in the series introduces Gabriel Knight, a financially struggling horror novelist based in New Orleans. Gabriel is following a series of homicides, dubbed "The Voodoo Murders" for their apparent voodoo overtones hoping to use the police investigation, led by Detective Mosely, as the basis of a new novel. However, as he draws deeper into the investigation, and his shop assistant Grace Nakimura performs historical research for him, Gabriel links the murder spree both to New Orleans' voodoo past and towards the beautiful and mysterious New Orleans socialite, Malia Gedde.
Gabriel also discovers connections between the case and a horrific recurring nightmare which has plagued him all of his life. His investigation brings him into contact with Wolfgang Ritter, a lost family relative in Germany. Wolfgang informs Gabriel that his family has an ancient heritage in investigating supernatural evil and that Gabriel himself has inherited the mantle of Schattenjäger, a sort of modern day Inquisitor. Gabriel discovers that his nightmares are the result of a curse brought upon his family by one of his ancestors, and that only by embracing his calling and solving the Voodoo Murders can he undo it.
Gabriel travels to Germany and Africa, before returning to New Orleans to confront those responsible for the murders and his family's suffering. The climax ends with Gabriel choosing between love and forgiveness or fulfilling his duty, offering two different dénouement's as a result.
The CD-ROM version featured voice talents of such well-known actors as Tim Curry as Gabriel, Mark Hamill as Mosely, Leah Remini as Grace and Michael Dorn as Dr. John, a proprietor of a voodoo museum in central New Orleans." (Wikipedia)
