Here is a nice quote from Malcolm Know of the Sydney Morning Hearald.
“In Robert Harris’s novel, The Ghost, a ghostwriter who produces the memoir of a retired politician (played in the 2010 movie by Pierce Brosnan) is murdered and replaced. Relationships between ghostwriters and their authors needn’t end up that badly but, as Harris writes, it can rarely be a straightforward relationship when its final act has to be that ”the ghost collapses like an empty suit of clothes”.”
