The way it's structured, the action would be set off from the speech with em dashes. Or you could indicate the pause with the ellipses, like you said.
Em dashes are fine if you want to use them; it's in the Chicago Manual of Style and everything. Like so:
“I think”--the deep-voiced man paused as if considering--“that one will do nicely.”
I like your original method, Gud. I know I've used it. I used to go with the dashes, but they're visually very abrupt, and I think it interferes with the musing quality of the statement.
You can always punctuate anything however you'd like. But a copy editor will change it.
My story is on the Daily Science Fiction website today.
Yay DANA!
It's awesome! And creepy! And great!
Awesome Dana! I'm heading over to give it some rockets!
Dana! That was awesome! Good on you!
And Sox, woo to the muthafockin' hoo!
I have news; I have my first essay up on Technorati: [link]
So a film school grad has asked if they can make a short, non-commercial film of a story they spotted on Daily Science Fiction - I'm mostly game, because hey, kind of fun! Anyone want to run pros/cons with me? Or have a lead on a suitable creative commons contract that's nc/ with attribution?
Also, go Erin on the essay !
