“Dear God,” Gareth said to himself. And then again, because never in his life had the moment more called for blasphemy: “Dear God.”

What sort of mess was he in now? A man couldn’t offer marriage to more than one woman at once. And while he might not have offered it to Mary Winthrop, the baron had done so in his name, and had signed documents to that effect. Gareth had no idea what this meant to his plans with Hyacinth, but it couldn’t be good.

Oh, bloody…Hyacinth.

Dear God, indeed. She’d heard every word.

Gareth started to run for the corner, then stopped himself, glancing up at the house to make sure that his father wasn’t watching for him. The windows were still dark, but that didn’t mean…

Oh, hell. Who cared?

He ran around the corner, skidding to a halt in front of the alley, where he’d left her.

She was gone.

Chapter 16

Still in the alley. Gareth is staring at the spot whereHyacinth should have been standing.

He never wants to feel like this again.

Gareth’s heart stopped.

Where the hell was Hyacinth?

Was she in danger? It was late, and even though they were in one of the most expensive and exclusive areas of London, thieves and cutthroats might still be about, and-

No, she couldn’t have fallen prey to foul play. Not here. He would have heard something. A scuffle. A shout. Hyacinth would never be taken without a fight.

A very loud fight.

Which could only mean…

She must have heard his father talking about Mary Winthrop and run off. Damn the woman. She should have had more sense than that.

Gareth let out an aggravated grunt as he planted his hands on his hips and scanned the area. She could have dashed home any one of eight different ways, probably more if one counted all the alleys and mews, which he hoped she was sensible enough to avoid.

He decided to try the most direct route. It would take her right on Berkeley Street, which was a busy enough thoroughfare that there might be carriages rolling home from the Mottram Ball, but Hyacinth was probably just angry enough that her primary aim would have been to get home as quickly as possible.

Which was just fine with Gareth. He would much rather see her caught by a gossip on the main road than by a thief on a side street.

Gareth took off at a run toward Berkeley Square, slowing down at each intersection to glance up and down the cross streets.

Nothing.

Where the hell had she gone? He knew she was uncommonly athletic for a female, but good God, how fast could she run?

He dashed past Charles Street, onto the square proper. A carriage rolled by, but Gareth paid it no mind. Tomorrow’s gossip would probably be filled with tales of his crazed middle-of-the-night run through the streets of Mayfair, but it was nothing his reputation couldn’t withstand.

He ran along the edge of the square, and then finally he was on Bruton Street passing by Number Sixteen, Twelve, Seven…

There she was, running like the wind, heading around the corner so that she could enter the house from the back.

His body propelled by a strange, furious energy, Gareth took off even faster. His arms were pumping, and his legs were burning, and his shirt would surely be forever soiled with sweat, but he didn’t care. He was going to catch that bloody woman before she entered her house, and when he did…

Hell, he didn’t know what he was going to do with her, but it wasn’t going to be pretty.

Hyacinth skidded around the last corner, slowing down just enough to glance over her shoulder. Her mouth opened as she spied him, and then, her entire body tensed with determination, she took off for the servants’ entrance in the back.

Gareth’s eyes narrowed with satisfaction. She was going to have to fumble for the key. She’d never make it now. He slowed a bit, just enough to attempt to catch his breath, then eased his gait into a stalk.

She was in for it now.

But instead of reaching behind a brick for a key, Hyacinth just opened the door.

Bloody hell. They hadn’t locked the door behind them when they left.

Gareth vaulted into another sprint, and he almost made it.

Almost.

He reached the door just as she shut it in his face.

And his hand landed on the knob just in time to hear the lock click into place.

Gareth’s hand formed a fist, and he itched to pound it against the door. More than anything he wanted to bellow her name, propriety be damned. All it would do was force their wedding to be held even sooner, which was his aim, anyway.

But he supposed some things were far too ingrained in a man, and he was, apparently, too much of a gentleman to destroy her reputation in such a public manner.

“Oh, no,” he muttered to himself, striding back to the front of the house, “all destruction shall be strictly in private.”

He planted his hands on his hips and glared up at her bedroom window. He’d got himself in once; he could do it again.

A quick glance up and down the street assured him that no one was coming, and he quickly scaled the wall, his ascent much easier this time, now that he knew exactly where to place his hands and feet. The window was still slightly open, just as he’d left it the last time-not that he’d thought he was going to have to climb in again.

He jammed it up, tumbled through, and landed with a thud on the carpet just as Hyacinth entered through the door.

“You,” he growled, coming to his feet like a cat, “have some explaining to do.”

“Me?” Hyacinth returned. “Me? I hardly think-” Her lips parted as she belatedly assessed the situation. “And get out of my room!”

He quirked a brow. “Shall I take the front stairs?”

“You’ll go back out the window, you miserable cur.”

Gareth realized that he’d never seen Hyacinth angry. Irritated, yes; annoyed, certainly. But this…

This was something else entirely.

“How dare you!” she fumed. “How dare you.” And then, before he could even begin to reply, she stormed to his side and smacked him with the heels of both of her hands. “Get out!” she snarled. “Now!”

“Not until you”-he punctuated this with a pointed finger, right against her breastbone-“promise me that you will never do anything as foolish as what you did tonight.”

“Unh! Unh!” She let out a choking sort of noise, the kind one makes when one cannot manage even a single intelligible syllable. And then finally, after a few more gasps of fury, she said, her voice dangerously low, “You are in no position to demand anything of me.”

“No?” He lifted one of his brows and looked down at her with an arrogant half smile. “As your future husband-”

“Do not even mention that to me right now.”

Gareth felt something squeeze and turn over in his chest. “Do you plan to cry off?”

“No,” she said, looking at him with a furious expression, “but you took care of that this evening, didn’t you? Was that your purpose? To force my hand by rendering me unmarriageable for any other man?”

It had been exactly his purpose, and for that reason Gareth didn’t say anything. Not a word.

“You’ll rue this,” Hyacinth hissed. “You will rue the day. Trust me.”

“Oh, really?”

“As your future wife,” she said, her eyes flashing dangerously, “I can make your life hell on earth.”

Of that, Gareth had no doubt, but he decided to deal with that problem when he came to it. “This is not about what happened between us earlier,” he said, “and it is not about anything you may or may not have heard the baron say. What this is about-”

“Oh, for the love of-” Hyacinth cut herself off in the nick of time. “Who do you think you are?”

He jammed his face next to hers. “The man who is going to marry you. And you, Hyacinth Bridgerton soon-to-be St. Clair, will never ever wander the streets of London without a chaperone, at any time of day.”

For a moment she said nothing, and he almost let himself think that she was touched by his concern for her safety. But then, she just stepped back and said, “It’s a rather convenient time to develop a sense of propriety.”

He resisted the urge to grab her by the shoulders and shake-barely. “Do you have any idea how I felt when I came back around the corner, and you were gone? Did you even stop to think about what might have happened to you before you ran off on your own?”

One of her brows lifted into a perfectly arrogant arch. “Nothing more than what happened to me right here.”

As strikes went, it was perfectly aimed, and Gareth nearly flinched. But he held on to his temper, and his voice was cool as he said, “You don’t mean that. You might think you mean it, but you don’t, and I’ll forgive you for it.”

She stood still, utterly and completely still save for the rise and fall of her chest. Her hands were fists at her sides, and her face was growing redder and redder.

“Don’t you ever,” she finally said, her voice low and clipped and terribly controlled, “speak to me in that tone of voice again. And don’t you ever presume to know my mind.”

“Don’t worry, it’s a claim I’m seldom likely to make.”

Hyacinth swallowed-her only show of nerves before saying, “I want you to leave.”

“Not until I have your promise.”

“I don’t owe you anything, Mr. St. Clair. And you certainly are not in a position to make demands.”

“Your promise,” he repeated.

Hyacinth just stared at him. How dare he come in here and try to make this about her? She was the injured party. He was the one who-He-

Good God, she couldn’t even think in full sentences.

“I want you to leave,” she said again.

His reply came practically on top of her last syllable. “And I want your promise.”
