It is not the first time that Victor Garcia Tur (Barcelona, ​​​​1981) works with Hitchcockian materials. In The birds (2015), his first novel, already made variations based on the homonymous film by the English filmmaker, based on the story of Daphne du Maurier. He took some plot motifs, part of the cast of characters, the general atmosphere and symbolic weight, and created a work of his own that, with the original, had as many points in common (an inexplicable change in the natural environment causes anguish and tension in the human landscape) that Turco felt and made specular divergences (Hitchcock is nowhere to be found). The merit of the novel is that it was able to play with the raw material without subordinating itself to it. Hitchcock was the starting point, a reference, not an idol to emulate or simply pay homage to.
