constructed house. These walls -- are you going,
gentlemen ? - these walls are solidly put
together;" and here, through the mere phrenzy
of bravado, I rapped heavily, with a cane which
held in my hand, upon that very portion of the
brick-work behind which stood the corpse”

Is this an example of Dramatic Irony, Verbal Irony, Situational Irony, or foreshadowing?
