To her further dismay, when he leaned forward to gather the reins, his arm brushed her breast, making her nipples tighten instantly. And the knowing gleam in his eyes told her clearly that his intimacy was intentional.

She refused, however, to let him win. She refused to be the kind of witless female who melted helplessly in his arms. As Dare set the curricle in motion, Julienne gave him back some of his own; she placed her gloved hand on his thigh as if for balance.

When his breath hissed through his teeth, she had to smother a gratified smile.

"If you don't want me to turn this vehicle around," he observed pleasantly, "and carry you up to your rooms to ravish you for the remainder of the afternoon, I suggest you remove your hand from my leg immediately."

Julienne complied, but she arched an eyebrow. "You think I would permit such an act of barbarism when I have no intention of allowing you even to kiss me again?"

He sent her an amused glance. "My apologies if I don't take your illusions too seriously. There's no doubt in my mind that I will make love to you again. And when I do, you will be more than willing-you'll be begging for it."

His arrogance made Julienne itch to take him down a peg. "I should think you would be aware by now of the danger in becoming my paramour. What if you were to truly fall in love with me?"

Dare had no witty retort for that. Instead he frowned and concentrated on his driving.

It was only midafternoon when they arrived at the park-Julienne had been unable to go later with a theater performance scheduled this evening-but the Row was already crowded with riders and carriages of every kind. Furthermore, Julienne discovered, they were the sole focus of countless pairs of eyes.

All London was watching their mating dance, it seemed.

"It amazes me," Julienne said, pasting a smile on her face to cover her exasperation, "how your ridiculous wager has created such a rabid interest in our affairs. It has grown to the point of absurdity."

"But the ton loves a spectacle," Dare replied. "Particularly a battle between worthy opponents. And we are well matched, I would say-the dazzling actress and the notorious rakehell. Although for now the betting books are giving me the edge."

Fortunately she didn't have to think of a retort, for she was hailed by one of her admirers.

They progressed at a snail's pace, since they both were continually greeted by acquaintances. A short while later, she heard Dare curse under his breath as they came across Riddingham driving a curricle.

The viscount looked just as displeased to see them together as he drew to a halt. After the initial pleasantries, Riddingham ignored Dare and addressed Julienne. "I hope you will permit me to take you for a drive tomorrow, Miss Laurent. We can try out my new pair." He nodded toward his horses, matched bays that looked fresh and impatient to be held standing.

"They are very handsome," Julienne said truthfully.

"They are a handful, but exceedingly fast."

"I don't suppose," Dare interrupted, "you would care to put them to a test?"

"A test? What are you suggesting?"

"Your pair against my grays."

"You are proposing a race?" Riddingham asked.

"You sound surprised."

"Perhaps you aren't aware, Wolverton, that I am a member of the Four-in-Hand Club?"

The club, Julienne knew, was made up of England's premier whips who regularly held races to exhibit their driving skills.

"I'm aware," Dare replied dryly. "And your expertise is doubtless unexcelled. But I think I can manage to provide enough sport to make a race worth your while. To keep it interesting, I propose that we each take a passenger-the lady of our choice. I intend to claim Miss Laurent, so you needn't bother asking her. But I'm certain Miss Upcott will oblige you."

Fanny Upcott was the Covent Garden actress Dare had invited to his house party.

"We can race to Hampstead Heath, if you like," Dare continued. "The posting inn at Primrose Hill would be a good place to start. The distance to the Blue Boar Tavern on the Heath would be… what… five miles? The winner buys dinner at the Blue Boar. What do you say, Riddingham?" When the viscount hesitated, Dare added with a smile, "Surely I'm not so intimidating as to make you refuse a challenge?"

"Not at all," Riddingham said testily. "Very well, I will race you. Barring rain, we will meet at ten o'clock tomorrow at Primrose Hill."

"Will you speak to Miss Upcott yourself, or do you need me to put in a good word for you?"

"I will do it," Riddingham snapped before turning his attention back to Julienne. "I am eager to see your portrayal of Ophelia in Hamlet this evening, Miss Laurent…"

Dare allowed her barely enough time to reply before he made their excuses and drove on, looking more than a little self-satisfied.

"What the devil was that about, challenging him to a curricle race?" Julienne asked in annoyance when they were out of earshot.

"I'm simply trying to shake things up a bit," Dare replied blandly.

"You are taking a great deal for granted by assuming I will accompany you. You're greatly mistaken if you think to have me at your beck and call-"

"I promise I am not taking you for granted, cherie."

"It certainly seems that way. You left me in no position to refuse. Your underhanded tactics are deplorable, Dare."

"Haven't you heard the adage that all is fair on the battlefield of love?"

His nonchalance irked her. "You are mangling your quotes again!"

Dare turned an innocent gaze on her. "Do you know, you are sure to get premature wrinkles between your eyes if you keep up that savage scowl?"

"Dare!"

His expression sobered in the face of her genuine anger, and he drew the curricle to a halt, giving her his full attention. "Forgive me, Jewel. I am deadly serious, despite my regrettable teasing. I desperately need your help with Riddingham. I beg you, will you please, please agree to accompany me on the race tomorrow?"

Mollified a slight measure by his seemingly earnest contrition, Julienne raised an eyebrow. "Desperately?"

A gleam of humor lit his eyes. "Yes, desperately."

"Very well. I will agree to help you. But you might consider asking next time before you volunteer me for your infamous games."

"Thank you, my love." Transferring the reins to one hand, he raised her fingers to his lips. The lazy, smoldering look from those eyes made her weak with wanting him.

Highly discomfited, Julienne drew her hand away "Are you trying to charm me out of my ill-humor?" she muttered.

His quick grin had a raffish quality. "But of course. I get my way so much more easily with charm."

Julienne raised her eyes to the sky and counted to ten before responding. "If that is so, then why aren't you using it on Riddingham? Why do I sense that you are deliberately attempting to rile him?"

"I told you, to agitate him into making a misstep." Shifting his attention to his horses, Dare set the vehicle in motion again. "In fact… we've had so few leads in the search for Caliban that I've decided to change tactics altogether. Stir the pot, you might say."

"Meaning?"

"I've begun putting out word that I am hunting the traitor."

Julienne frowned at his admission. "Isn't that potentially dangerous? If Caliban is as ruthless as you say, could you not be making yourself his target?"

"It would be worth the risk if I could draw him out." When she remained silent, Dare shot her an arch glance. "Can it be that you are actually concerned for my skin, love?"

She was gravely concerned, although she had no intention of admitting it to him. "But of course," she answered lightly. "If something untoward befell you, then I would have no chance to win our wager."

To her surprise, Dare's expression grew intensely somber. "This is a trifle more serious than our wager. Three weeks ago a young woman was found drowned. She was companion to Lady Castlereagh…"

Julienne listened in shock and dismay as he told her about Alice Watson's death and the reasons for believing she'd been seduced to gain access to Lord Castlereagh's letters and then murdered.

Her brow furrowing, Julienne searched Dare's face. "Do you honestly think Riddingham could be so heinous as to murder an innocent girl?"

"I don't know. It would help to discover whether he even knew Alice Watson, and whether he had the opportunity to woo her. I'd give a monkey to know where he was on March seventh when she was killed. It could prove-or perhaps even disprove-his complicity."

"Is there anything I can do?" Julienne offered. "Perhaps I could discreetly question Riddingham and see what I can learn."

"No," Dare said curtly, "I will handle it."

He felt Julienne studying him. "A few days ago you suggested I take him for my lover so I could try to ferret out his secrets."

"A few days ago I was behaving like a jealous ass."

"And you are not now?"

His mouth curved in a reluctant grin. "I admit I harbor a measure of possessiveness where you're concerned. And jealousy isn't my only reason for declining your offer to investigate. If Riddingham is a killer, I don't want you anywhere near him. You should dress warmly tomorrow," Dare warned, changing the subject. "The wind will be wicked with the pace I intend to set."

She sighed. "What time should I be ready?"

"I'll call for you in the morning at half past nine… Unless you mean to invite me to spend the night with you to save time…?"

"Do you never give up?" Julienne said in exasperation.
