The main aspects of the model as set out in the previous chapters are brought together to explore humour-related effects in three case studies. The first study investigates the recognition and appreciation of parody in Aberystwyth Mon Amour by Malcolm Pryce. The second investigates shifts in narratorial voice in Man at the Helm by Nina Stibbe and the effects this has on humour construction. The third explores how humour can be recognised, appreciated, and shared with a character in a serious situation in Crooked Heart by Lissa Evans.
