ALP's Letter becomes the focal point as it is analysed in detail in I.5. This letter was dictated by ALP to her son Shem, a writer, and entrusted to her other son Shaun, a postman, for delivery. The letter never reaches its intended destination, ending up in a midden heap where it is unearthed by a hen named Biddy. Chapter I.6 digresses from the narrative in order to present the main and minor characters in more detail, in the form of twelve riddles and answers. In the eleventh question or riddle, Shaun is asked about his relation to his brother Shem, and as part of his response, tells the parable of the Mookse and the Gripes.
