How are the stories in Dubliners interlinked?

Look for examlpes of the "seven deadly sins" portrayed in individual stories.

For example "lust" in "The boarding House"

"sloth" in "counterparts"

"envy" in "A Little Cloud"

"wrath" in "Counterparts"

"pride" in "Clay

Also many of the stories have allusions to Dante

The best study on the subject is "The Unity of

dubliners" by  Brewster Ghiselin" which can be found in "Dubliners" Text Criticism and Notes edited byRobert Scholes and A walteon Litz

Most of the characters are paralized in some way, spiritually

emotionally, vicitms of circumstance.
