The main target of Lindskoog's writing was Walter Hooper, Lewis's literary co-executor who edited most of Lewis's posthumous work. Lindskoog points out that Hooper's relationship with Lewis was overstated in some of the publications that he edited, and she argues that several works published under Lewis's name were in fact by Hooper.
C. S. Lewis' stepson, Douglas Gresham, denies the forgery claims, saying that "The whole controversy thing was engineered for very personal reasons... Her fanciful theories have been pretty thoroughly discredited." It is not clear if Gresham has ever been in a position to know the details of the literary controversy or the nature of Hooper's acquaintance with Lewis during the closing months of Lewis' life. It is clear from the diaries of Warren Lewis that Lewis' brother distrusted Hooper, whom he viewed as a dishonest interloper in the 1960s. Lewis scholars are divided about the merits of Lindskoog's charges, but some of them have since been disproved by discovery of Lewis's own typescripts. Much of her perceived animosity against Hooper may have been derived from disappointment that she was not given any role in dealing with his literary legacy, though Lewis acknowledged her as knowledgeable about his bibliography. The controversy was analysed by Nicolas Barker in 'Essays in criticism' (see reference), where he calls Lindskoog's work "a poisoned book".
