This book is neither biography nor a conventional film critique. Rather, the text explores aspects of Hitchcock's work in relation to theories drawn from the social sciences and philosophy. The various chapters focus not on specific films, but on broader ideas central to Hitchcock's work. There is, for instance, a chapter on his idea of the MacGuffin in which I use Ernesto Laclau's theories of equivalent substitution to explain how the MacGuffin functions in Hitchcock's works. There is also a chapter on his notion of 'pure cinema' which moves from the idea of purity as an anthropological concept to consider purity in relation to current debates regarding so-called hybrid media, and Hitchcock's relevance to these issues in respect of his dissatisfaction with the advent of sound to the cinema world. Broadly speaking, the book uses Hitchcock's films to illustrate ideas in the social sciences and philosophy and uses those same ideas to illustrate aspects of Hitchcock's films.

McCarron approaches the work of Alfred Hitchcock in a way that is unique in the world of film critique. Rather, than provide a biographical overview, or consider Hitchcock's work in the context of conventional film criticism, McCarron uses Hitchcock's films to illustrate ideas at play in the social sciences and philosophy even as he uses those same ideas to illustrate central aspects of Hitchcock's films. In short, while McCarron focuses on many of Hitchcock's most celebrated films, his broader concern is with a series of ideas crucial to Hitchcock's work as an innovative artist of the cinema. For example, McCarron interrogates the idea of the MacGuffin, Hitchcock's famous term for the motivating issue in a film's narrative. However, there is far more to the idea of the MacGuffin than is found in Hitchcock's description, as McCarron shows how political theorist Ernesto Laclau's theory of equivalential substitution effectively explains how the MacGuffin functions as a device to bridge the divide between the film's exegesis and the audience's emotional engagement in the story. In a similar vein, McCarron undertakes a close reading of Hitchcock's theory of 'pure cinema,' indicating that while the concept is widely embraced by Hitchcock scholars, rarely do those scholars agree on what Hitchcock ultimately intended by the phrase. Tracing the development of the concept across the years, McCarron shows how Hitchcock's theory of pure cinema resonates with anthropological concepts of purity and even finds a place in current debates regarding so-called hybrid media. McCarron further explores Hitchcock's alleged moralism, showing how the problem of moral agency was often treated in Hitchcock's films as a highly complex and decidedly ambiguous condition. McCarron indicates the importance of re-viewing Hitchcock's films from points of view that plainly show that Hitchcock is not properly understood when simply described as 'the master of suspense,' as his films are of enduring interest for a range of reasons that go well beyond their relevance for traditional film studies. Interpretations of his films gain in power and scope when we extend our analyses to the intricate interpretations of his work as it touches on subjects as diverse as politics, feminism, rhetoric, and philosophy. McCarron treats these larger intellectual constellations in considerable detail, bringing a fresh perspective to the study of the famed director's work.
