The theoretical underpinning to the concept of identity is the central topic of Chapter 5, where we examine particular facets of identity such as the performance of age, relationships and communities of practice. Keeping in mind our view of identity as being continuously negotiated through discursive practices, we focus here particularly on how age is treated as a relevant identity category by participants, and how relationships between adult offenders and child victims are performed. We probe the question of how these performances are situated in the wider social context, and in relation to other, more recognisable types of relationship that might be relied upon as resources.
