The irony is found in the end of the poem. "And Richard Cory one calm summer night / Went home and put a bullet through his head." After describing Richard Cory as the man everyone else wanted to be, the author suddenly twists the poem, showing Richard Cory's suicide. "Calm" increases the irony, because it gives a false illusion of peace and contentment, only to be shattered by Richard Cory "putting a bullet through his head." Its situational irony.
