The thing about dialogue tags is that you don't HAVE to use them. If you only have two people in the conversation, you know which one is speaking when you're careful about interspersing action. Your readers will follow it.
At the risk of sounding conceited, this is from A Touch Of Sin, my latest Siren contract. Bear in mind it's erotic romance and readers expect the lust, so I've taken out one sentence, without ruining flow. But notice how I avoid using dialogue tags. You have action here and there which gives you a visual, and there are only two people speaking - the heroine (Savannah) and one of the heroes (Ethan) so you can follow who is saying what. I've already set up in previous paragraphs it's only them, out on a date. We're in Savannah's POV.
He arrived at her home five minutes early, and Savannah was ready. “Hi there. You look wonderful.” He did indeed. He wore a perfect suit that was light enough for warm weather, but not so formal that she felt underdressed. He smelled incredible, and she wanted to run her fingers through his dark hair. In the evening light his blue eyes looked like sapphires.
“Um…so do you. Wow. Turn around. Let’s have a look.”
Savannah grinned, then twirled slowly.
“Is that Furstenberg?”
Her eyes widened. “It’s a knock-off, but tell me why you know designers.”
He laughed, soft and easy. “My sister is a buyer for Saks in New York. You have no idea the endless emails I have to endure, complete with pictures.”
She linked her arm in his as they descended the front steps toward his Porsche. “Is that where you’re from?” No one knew.
He shook his head. “Jersey.”
“As in New Jersey?”
He opened the passenger door and gave her a grin. “Yes. Sorry. I’ve been gone for years but I still speak like I’m there, don’t I?”
“Well, we all guessed it was Easy Coast, but no one was entirely sure where.”
He slid into the driver’s seat and glanced at her sideways. “Now you know my deep, dark secret. What will you do with it?”
His gaze traveled down to where the fold at the bottom of her dress had fallen open, exposing her thighs about halfway up. Savannah didn’t cover her legs. Instead she held his gaze steady. “I’ll take it to my grave.”
He shook his slightly as if he’d zoned out for a second, and then he backed out of the driveway. “It’s not that important, is it? I mean not being from here?”
“Everyone knew you weren’t from here the moment you spoke.”
He laughed again. “Touché. Four years at Vandy and five years in Ohio didn’t kill the accent I guess.”
“Not even close. So, Vandy, eh? Great med school.”
“Did you do your residency in Ohio then?”
“Yes. In Cleveland, at MetroHealth Medical Center.”
She nodded, having no clue about that hospital other than hearing the name a few times in her nursing career. “And now you’re here. What do you think of Sin?”
He grinned again. “The hospital, the town, or the concept?”
Oh my! “Let’s start with the town and work our way forward.”
Was that a soft moan she’d just heard? “I like the town. I really do. Jersey is so big, noisy, and dirty. I can hear the crickets at night here, and the stars are beautiful.”
“I agree.” She shifted in her seat to face him as they made their way onto Interstate 24. “Where in New Jersey are you from?”
“Alpine. It’s on the Hudson across from Yonkers.”
“And now the hospital. It must seem very small town compared to Vandy and MetroHealth.”
“Are you familiar with MetroHealth?”
“Only by reputation.”
“I wanted a change of pace which is why I jumped at the chance here. And taking care of people who have been hurt is the same everywhere.”
“Do you plan on staying, or will you go somewhere else to become an attending? Or do you plan on going into private practice?”
He cocked his head to one side. “I’m not sure yet.” Then he gave her legs another glance. “Depends on whether or not I find a reason to stay.”
