Ian caught Mac watching him as they ate and threw him a triumphant glance. Bloody cheek. After his brothers had struggled to reach Ian for years, two beautiful women had opened the world to him—Isabella with the love of a sister; Beth with the love of a wife. And damn it, wasn’t Ian smug about that?

Mac retired to his studio after supper and started preparing for the next morning. He snatched a few hours of sleep on the divan he’d set up there, then rose and dressed in his painting kilt, boots, and kerchief to protect his hair long before Isabella was due to enter.

When, at precisely nine o’clock, Isabella did open the door without knocking, Mac was bent over his worktable mixing paints. He didn’t look ’round as she closed the door. Something silken rustled, and his hands started to shake.

“Good heavens, it’s actually warm in here,” Isabella said in wonder. “I wore my warmest dressing gown, but it seems you stoked the fire.”

Mac kept his gaze resolutely on the paint he mixed. “Bellamy did. Can’t have her ladyship catching her death, can we? Lock the door, love, unless you want members of my family blundering in to catch you in your altogether.”

The lock clicked, and Isabella’s dressing gown whispered as she crossed the room. “Am I to sit here?”

Mac busied himself mixing the exact shade of yellow that had made him famous. “Mmm hmm.”

“I’ll just make myself comfortable until you’re ready, then.”

Mac worked his palette knife through the paint in hard strokes. He dribbled in some green—far too much. Damn. He threw the batch into a scrap bucket and started again.

“My ride this morning was quite fine, thank you,” Isabella said, the blasted dressing gown rustling some more. “Such brisk weather. Refreshing.”

A touch more cadmium yellow and it would be perfect. “Mmm hmm.”

“Hart rode with me. We had a long conversation. He asked me if I thought it a good idea if he married again.”

Mac’s muscles worked as he kneaded the large glob of paint to just the right consistency. Anyone who claimed painting wasn’t hard work was a bloody fool.

Isabella went on. “We also saw a few pigs flying. Which likely explains what I’m doing up here with you in nothing but a dressing gown.”

Mac finally turned.

Isabella was sitting on the edge of the chaise like a debutante at her first tea party. She had her feet primly on the floor, her hands in her lap. Her red hair was pulled into a simple knot, a few tendrils escaping it. The dressing gown was voluminous, but the silk clung to her bare body, and a curve of breast peeked coyly from the opening.

Oh, God.

Mac had set the backless chaise in front of a crimson brocade curtain. One end of the chaise was raised so a lady could recline, half-sitting, half-lying. Mac had piled it with white silk draperies and cushions of brilliant gold. A bowl of bright yellow roses stood on the table next to it. Some of the rose petals had already drooped and fallen.

He drew a sharp breath and made himself turn away. “Lie down and pull the white cloths over your middle. I’ll begin in a minute.”

He’d barked similar instructions at many a model, feeling nothing as they slid out of their garments and draped themselves over whatever piece of furniture he’d provided. To Mac models were things of light and shadow, lines and colors. The best ones could breathe life into those lines and colors—without talking, wriggling, whining, or trying to flirt with him.

He moved to his easel with his charcoal pencil, keeping his gaze on the canvas. Out of the corner of his eye, he saw Isabella calmly undo the fastenings that held her gown closed. His heartbeat rocketed.

You’ve painted her before. This is a picture, nothing more.

“Like this?”

He had to look—how was he supposed to paint her without looking at her?

Mac looked. And stifled a groan.

Isabella lay propped on one elbow, her body half-turned toward him, the white sheet trickling across her abdomen. Her creamy breasts were tipped with dusky red, and coppery orange prickled from between her thighs. When they’d first married, Isabella had been eighteen, and her breasts had been high and round, firm little peaches. Six and a half years later, her breasts hung a little lower and her hips were rounder—womanly curves replacing the straight lines of the girl. She was so beautiful he wanted to weep.

“Mac?” Isabella lifted her hand and snapped her fingers. “Are you still here, Mac?”

“Mesmerized.” Mac made himself give her a clinical glance, as though she were a bowl of fruit he’d set up to paint. Fruit. Lord help me. “This is an erotic picture. Your pose is too tame.”

“Well, I don’t know much about erotic pictures, do I?”

Mac steadied his voice with effort. “Pretend you’ve been ravished repeatedly by your lover and then left on your own.”

“Ah.” Isabella sat up, tucked her feet under her, and mimed writing something on her lap.

Mac stared. “What the devil are you doing?”

“Writing a letter to my solicitor, naming my ravisher in a suit, and outlining the amount I expect to receive in damages.”

His heart started thumping again. “Amusing, love. Now lie back down. And sprawl.”

Her brows arched. “Sprawl? How does one sprawl?”

“Do you mean to tell me that the art of sprawling was never taught at Miss Pringle’s Select Academy?”

“Neither was taking off one’s clothes to be painted,” Isabella said. “Nor how one looks after one is ravished. Perhaps I should speak to Miss Pringle about amending the curriculum.”

Mac laughed. “I dare you. And please let me be there when you do.”

“I imagine that by ravished, you mean disheveled.” Isabella rubbed her hand through her hair. More tendrils fell from the bun and straggled across her cheek.

She was going to kill him. They were speaking rapidly and lightly, as though none of this truly mattered, but both of them were nervous. Or at least Mac was. Isabella, as always, looked cool and composed.

“More than disheveled,” he said. “You have been thoroughly spent by a night of grand passion.”

“I will have to use my imagination then. I’m not sure what that is like.”

Her sly smile and the sparkle in her eyes snapped Mac’s control. He tossed down his pencil and came around the easel to stand over her. “Little devil.”

“I said it in jest, Mac. I suppose I’ve had one or two nights of grand passion.”

“You, my dear, are coming dangerously near to . . .” He stopped, unable to complete the sentence.

Isabella’s lips curved. “Dangerously near to what, my lord?”

A morning of grand passion? She was his wife, his other self, and they’d thrown off their clothes and their restraints. Why should he stop himself?

“A tickling,” he finished. “You should be tickled until you can no longer make fun of your doddering old husband.”

Her glance moved down his body like a lick of flame. “I would never apply the adjectives doddering or old to you.”

Mac found it difficult to breathe. Or talk, or think. He seated himself on the edge of the chaise and yanked the crumpled sheet across her stomach. “I did promise to have these pictures done before Michaelmas. Now, sprawl, my dear. Arm overhead like that, leg hanging like this, sheet tangled and pushed aside.”

Isabella let him move her arm and leg without a murmur. Mac’s hands shook as though he were palsied.

“If a lady were truly sleeping after a grand passion,” Isabella said, “she’d bundle up in the sheet so as not to catch her death of cold. After warming herself with a nice cup of tea.”

“You are far too exhausted for that. Barely awake at all.” Mac patted her hip. “Move that a little off the edge.”

“That? Are you implying that I am stout, Mac Mackenzie?”

“The word never left my lips, my petite angel.”

“Humph. Plump, perhaps? Portly, even?”

He wanted to tell her how much he adored her voluptuousness, her body that had grown even more beautiful since he’d seen it last. She’d actually become a little thinner since her departure, and he’d noticed that her appetite had lessened a bit, which worried him.

But Mac had been painting women since age fifteen, and he knew how sensitive they could be to any even imagined change to their waistline. A wise artist never mentioned it unless he wanted to lose a day’s work. He’d always been thankful that Isabella was much more sensible about her body, but even joking as she was, he knew better than to tell her he preferred her curves to the bodies of women who slimmed themselves into sticks.

“My love,” Mac said, “you have the finest, as the French say—derriere—imaginable.”

“Liar.” Isabella hooked her finger on the waistband of his kilt. “Take this off.”

Mac froze. “What? Why?”

“You have seen what I have become. Perhaps I would like to see whether your derriere has grown broader with time.”

What she would see was a cock that had elongated into a rigid pole. She could hang her St. Leger Ladies’ Day hat on it . . . and oh, Lord, why did he just think of that?

“You saw me in the bath, at your house in London,” he said. “And I lifted my kilt for you in your drawing room.”

“A brief glimpse, both times.” Isabella tugged harder on the waistband. “Come now, Mac. Turnabout is fair play.”

Mac decided he’d strangle whoever had invented that saying. He drew a deep breath, unpinned and unfastened the kilt, and let the woolen folds drop to the floor.

Isabella’s eyes grew round. “Oh. My.”

Mac put his knee on the chaise, swung himself on top of her, and lowered his face to hers. “Did you think you could lie here like this without me responding? I’ve been hard for you, my dear, since you barged into my house and actually spoke to me after three and a half years of silence.”
