A startled look flashed through Mac’s copper-colored eyes, but he covered it with another cool bow.

“Chaperoned by a nanny and a baby,” he muttered. “Ah, well.”

The weather was so fine that Hyde Park teemed with people. Mac dropped the pretense of being the proper suitor, tilted back his hat, and insisted on pushing the pram. Isabella strolled beside him, enjoying the sight of her broad-shouldered, kilted husband pushing a baby carriage. Miss Westlock dropped behind, a nanny indulging the master and mistress.

The Rotten Row flowed with horses and carriages, and the other paths carried families, walking couples, and nannies with children. Aimee sat up in her pram, holding onto the sides and looking about with interest. She was a robust child—hearty, Miss Westlock called her—and enjoyed peering at the world.

What Aimee felt about losing her mother, Isabella couldn’t fathom. Perhaps the child was too young to understand what had happened, but all in all, she seemed to accept with her change in fortune. She was happy to bestow loving kisses on both Mac and Isabella, and though she made it clear that she preferred Mac, she was now content to be left alone with either Isabella or Nanny Westlock.

Isabella wondered whether Payne, her true father, would attempt to wrest Aimee back from them. Isabella didn’t understand whatever strings Mr. Gordon had pulled to make the adoption legal, but he’d assured them that all would be well. Isabella still worried, though. Aimee did not need to be taken by a lunatic who set fires to houses and stalked women in parks.

“Mac, old thing!” A man’s voice rang out and Isabella looked up to see four gentlemen bearing down on them.

She stifled a sigh. They were Mac’s friends from Harrow and Cambridge, the boys who had worshipped Mac as their leader-in-crime during their school days. They were grown men now, but they’d collectively remained the wild tears who’d done anything to gain Mac’s approval.

The one who walked in front, a short, rather slender young man with blond hair, had become Marquis of Dunstan at age twenty-two. His Christian name was Cadwallader, and they called him Cauliflower or Cauli for short. The others were Lord Charles Summerville, the Honorable Bertram Clark, and Lord Randolph Manning. None of these gentlemen had passed Isabella’s father’s rigorous screening as possible suitors for her, and it had been these four gentleman who’d originally wagered that Mac would never “crash” Lord Scranton’s ball and dance with his virginal daughter.

“Do my eyes deceive me?” Lord Charles Summerville screwed a monocle into his left eye and peered through it. “Good Lord, it is Mac Mackenzie walking a baby. From where did you steal the damned thing? Paying off a wager, are you?”

“This is my daughter,” Mac said coolly. “Miss Aimee Mackenzie. I’ve just adopted her. Pray watch your language in front of her as well as in front of my wife.”

Summerville guffawed while Bertram Clark bowed to Isabella. “Ah, the lovely Lady Isabella. How delightful to see you again. You dazzle mine eyes, my lady.”

Lord Randolph Manning gazed unsteadily at her. “I thought you well rid of this blackguard, Izzy. I’m devastated you’ve never sought solace in me. My door is always open, you know.”

“Randy Randolph,” Cauliflower chortled.

“Stubble it,” Mac said. “Insult my wife again, Manning, and your eye will learn the exact texture of my gloved fist.”

Manning blinked. “Good lord, what did I say?”

“Forgive my Lord Randolph,” Bertram Clark said to Isabella. Mr. Clark had the best manners of the lot but also the reputation for being the most dissipate. “He’s drunk, he’s an idiot, and he swoons at your feet. We all do, as you know.”

“It’s quite all right,” Isabella said. “I’m well used to his vulgar manners.”

The four men burst out laughing. “As erudite as ever,” Lord Charles said. “We’ve missed you, my lady. In truth, Mac, what are you doing with a baby?”

“I answered you. I adopted her.”

Manning blinked his hazy eyes. “Dropped a by-blow, did you, Mac? Your lady wife is a most forgiving woman.”

Cauliflower gaped, and Bertram Clark grabbed the back of Manning’s collar. “That’s it. Time to sober you up, old man.” He dragged Manning off, Manning spluttering and continuing to ask what he’d said wrong.

“Cauli,” Mac said in a quiet voice. Cauliflower, who was a foot shorter than Mac, turned red but gave Mac his attention. “Know this: Aimee is not my by-blow, and she will be raised as a proper young lady. Any other gossip is to be squelched. You know the truth, and I expect you to uphold it. You too, Charlie. Tell the others.”

Cauliflower touched his forehead. “Right you are, chief. You can count on us. But by the bye—since wagers were mentioned—what about the one we made before you went to Paris? You know about the . . . ?” He trailed off, making a painting motion with his hand.

“The erotic pictures?” Mac finished. “Fear not, Isabella knows all. I keep nothing from my wife, as you know. I am working on them.”

Charles shook his head. “Time’s running out, Mac, old boy. I hope you know some merry tunes to sing with the temperance band.”

“I’ve been told I have a nice baritone.” Mac’s words were light, but Isabella saw a muscle tighten in his jaw, his temper rising.

“We’ll make certain every member of the club is out to watch you and cheer you on. It will cause quite a stir.”
