In his book of interviews with Hitchcock, François Truffaut notes that the novel "cheats" by having extended conversations between Norman and "Mother" and stating what Mother is "doing" at various given moments.
U svojoj knjizi intervjua s Hitchcockom, Francois Truffaut piše da knjiga zapravo "vara" čitatelja zbog silnih dugih razgovora između Normana i "Majke" te opisa što Majka "radi" u određenim trenucima.
