Ran into a particular problem in a new story. I understand that em-dashes are often used for interrupted speech, but I'm looking to have someone continue after they were interrupted, and I'm looking for advice on the best strategy.
The segment I have, so far, reads:
"Apparently you met at the Woodland Community Gardens and—"
"Ah, now I know which Peter you're referring to."
"and he wrote the paper to object to its reporting.
Should I put an em-dash at each end—both when the first speaker is interrupted and when he resumes, or should I have it at the end of each line—to show they were both interrupted.
I'm trying to show the character continuing on despite the interruption, rather than their stopping and starting again.
Any ideas on what reads the best?
