Deception and Appearance

Deception drives the plot in 'In the Shadow of the Glen,' where Dan fakes his death to test his wife, and in 'The Tinker's Wedding,' where characters manipulate the priest, revealing how appearances mask hidden motives.

Mary hides the porter bottles and tries to deceive the priest into drinking, while Sarah and Michael present themselves as hardworking poor to gain sympathy, revealing the gap between appearance and reality.

Sarah and Michael attempt to present a respectable front for their wedding, but Mary's theft of the tin can and substitution with empty bottles exposes their deceit, leading to the priest's refusal.
