Your experiences in the Neath have given you plenty of material for a lecture on the motivations and behaviour of the iniquitous element. You cover the arsonist, the burglar, the honey-fiend, the revolutionary and the smuggler. Used to dry academic fare, the students are rapt by your earthy tales of the shenanigans of the Neath. The professors are incensed that your somewhat racy tales violate several of their pet theories and your lecture is stopped in mid-flow, to the great annoyance of the students. You continue your talk later in a nearby hostelry, but payment from the Dean is not forthcoming.
