Gregory Miller’s book begins with a theoretical discussion of the importance of ‘reputation’ in international politics, before analysing its role in four case studies taken from European diplomacy before 1914. To a quite unusual extent, his study consists of an extended critique of a single book – and one published in the same series with the same editors – Jonathan Mercer’s Reputation and International Politics. Three of Miller’s case studies were used also by Mercer, and the two writers draw on very similar source material. Miller repeatedly cites and refutes Mercer’s work, up to four times on a single page (p. 176). To a large extent Miller’s book must be read as a foil to an earlier contribution rather than as a stand-alone study.
