This paper focuses on Peter Ackroyd’s unique type of psychogeographical writing. Therefore, apart from an overall elaboration on his works about London, it addresses his historiographic metafictional novels Hawksmoor (1985) and The House of Doctor Dee (1993). These esoteric novels provide insight into Ackroyd’s writing about the city in different time periods and make it possible to delve deeper into what this paper argues is his distinctive manner of implementing the notions of psychogeography. At the same time, it draws parallels from classical and contemporary psychogeography where appropriate and highlight his utilisation of it. The main aim of this paper is to reveal the ways in which Peter Ackroyd uses walking in the city to reflect its manipulative power over his characters which results in the transformation of their identities.
