“Quiet!”

She shut her mouth.

Blake studied her for several moments. Something about her wasn't right. Carlotta De Leon was Spanish … well, half-Spanish at least, and this girl looked English through and through. Her hair couldn't be called blond, but it was definitely a light shade of brown, and even in the dark night he could see that her eyes were a clear bluish-green.

Not to mention her voice, which was tinged with the pommy accents of the British elite.

But he'd seen her sneaking out of Oliver Prewitt's house. In the dead of night. With all the servants dismissed. She had to be Carlotta De Leon. There was no other explanation.

Blake—and the War Office, which didn't precisely employ him but did give him orders and the occasional bank draft—had been after Oliver Prewitt for nearly six months now. The local authorities had known for some time that Prewitt was smuggling goods to and from France, but it was only recently that they had begun to suspect that he was allowing Napoleonic spies to use his small boat to carry secret diplomatic messages along with his usual cargo of brandy and silk. Since Prewitt's boat sailed from a little cove on the southern coast between Portsmouth and Bournemouth, the War Office hadn't originally paid much attention to him. Most spies made their crossings from Kent, which was much closer to France. Prewitt's seemingly inconvenient location had made for an excellent ruse, and the War Office feared that Napoleon's forces had been using him for their most delicate messages. One month ago they had discovered that Prewitt's contact was one Carlotta De Leon—half-Spanish, half-English, and one hundred percent deadly.

Blake had been on the alert all evening, as soon as he'd learned that all of the Prewitt servants had been given the night off—an uncommon gesture for a man as notoriously stingy as Oliver Prewitt. Clearly something was afoot, and Blake's suspicions were confirmed when he saw the girl slip out of the house under the cover of darkness. So she was a trifle younger than he'd supposed—he wasn't going to let her guise of innocence deter him. She probably cultivated that look of blooming youth. Who would suspect such a lovely young lady of high treason?

Her long hair was pulled back into a girlish braid, her cheeks had that pink, well-scrubbed look, and …

And her delicately boned hand was slowly reaching down toward her pocket.

Blake's finely tuned instincts took over. His left arm shot out with startling speed, knocking her hand off course as he lunged forward. He hit her with all his weight, and they tumbled to the ground. She felt soft beneath him, except, of course, for the hard metal gun in her cloak pocket. If he'd had any doubts of her identity before, they were now gone. He grabbed the pistol, shoved it in his waistband, and stood back up, leaving her sprawled on the ground.

“Very amateur, my dear.”

She blinked, then muttered, “Well, yes. That's to be expected as I'm hardly a professional at this sort of thing, although I do have some experience with …”

Her words trailed off into an unintelligible mumble, and he wasn't at all sure if she was speaking to him or herself. “I've been after you for nearly a year,” he said sharply.

That got her attention. “You have?”

“Not that I knew who you were until last month. But now that I've got you, I'm not letting you go.”

“You're not?”

Blake stared at her in irritated confusion. What was her game? “Do you think I'm an idiot?” he spat out.

“No,” she said. “I've just escaped from a den of idiots, so I'm well familiar with the breed, and you're something else entirely. I am, however, hoping you're not a terribly good shot.”

“I never miss.”

She sighed. “Yes, I feared as much. You look the sort. I say, do you mind if I get back up?”

He moved the gun a fraction of an inch, just enough to remind her that he was aiming at her heart. “Actually, I find I prefer your position on the ground.”

“I had a feeling you would,” she muttered. “I don't suppose you're going to let me go on my way.”

His answer was a bark of laughter. “I'm afraid not, my dear. Your spying days are over.”

“My spying—my what?”

“The British government knows all about you and your treasonous plots, Miss Carlotta De Leon. I think you'll find we do not look kindly upon Spanish spies.”

Her face was a perfect picture of disbelief. God, this woman was good. “The government knows about me?” she asked. “Wait a moment, about who?”

“Don't play dumb, Miss De Leon. Your intelligence is well-known both here and on the continent.”

“That's a very nice compliment, to be sure, but I'm afraid there has been a mistake.”

“No mistake. I saw you leaving Prewitt Hall.”

“Yes, of course, but—”

“In the dark,” he continued, “with all the servants dismissed. You didn't realize we'd been watching the hall, did you?”

“No, no, of course I didn't,” Caroline replied, blinking furiously. Someone had been watching the house? How had she not noticed? “For how long?”

“Two weeks.”

That explained it. She'd been in Bath for the past fortnight, attending to Oliver's sickly maiden aunt. She'd only returned this afternoon.

“But that was long enough,” he continued, “to confirm our suspicions.”

“Your suspicions?” she echoed. What the devil was this man talking about? If he was insane, she was in big trouble, because he was still pointing a gun at her midsection.

“We have enough to indict Prewitt. Your testimony will ensure that he hangs. And you, my dear, will learn to love Australia.”
