This chapter draws on Jacques Derrida's concept of destinerrance, the sense in which meaning is ‘destined to err and to wander’, as a way of understanding the unstable and ultimately horrific process of misreading sign and symbol in Don't Look Now (1973). John Baxter's misreading of the murderous woman as his lost daughter, but also his misreading of colour and image, of his wife, of the strange psychic women they meet, of himself and his place in the world, of the dangerous spaces he inhabits, and even of time itself, all contribute to the film's uncanny sense of his environment as simultaneously loaded with and empty of meaning. John might ‘feel’ that he is ‘a detective’, but ultimately, he is a failed one, since his misreading of the ‘clues’ he perceives lead to the perpetuation rather than the prevention of crime and trauma. It is in the space of these misreadings, of failing to see in time, that the film's horror, its capacity to scare, resides, since it insists on the suspension rather than the resolution of trauma. The film's misreadings, then, are ultimately instructive or didactic, but in moving away from the conservative restoration of order which is typical of the Gothic narrative, Don't Look Now's iteration of horror remains open.
