The Shoe of the Roof is a thought-provoking novel about faith and the thin line between madness and reality. Thomas Rosanoff is a brain-research grad student. His father, Dr Rosanoff, is a famous psychiatrist who gained his notoriety by studying his son’s life in great detail and publishing in “The Boy in a Box.” Having a famous father is a double-edged sword for Thomas: he gets away with a lot at the university, but he has to put up with a lot of ribbing. Using his father’s name, Thomas kidnaps three patients from the mental hospital, who think they are Jesus. He wants to experiment with them to prove that bringing them together will cure them. He believes that they will sort out among themselves that three Jesuses can’t exist all at once, and so at least two of them will have to cure themselves of their delusion.
You need to read Shoe to find out what the title means. Also, read Ferguson’s 419; it won a well deserved Giller Prize. There was an excellent Peter O’Toole movie of a similar theme from 1972, The Ruling Class. O’Toole was a British lord who believed he was Jesus. I may be available online.
