“Almost a year, Madame. They become lovers at the New Year, at a ball at the house of the Governor, in the pantry where the silverware is cleaned. I found some of the cleaning-sand in her petticoat-lace afterwards. But since first she is introduced to him, in the summer at a picnic in honor of the officers of the regiment, she has—what is the word? She has set her hat in his direction.”

“Did she love him?” asked Abigail. “Or he her?”

One corner of that wry little mouth turned down: Eh, bien, what will these Americans think next? “Oh. Madame. He was quite fond of her—men usually are, if a good-looking woman will consent to go to bed with them. I have heard he is genuinely grieved, and swears that he will hang every Son of Liberty in the colony for the crime. But she—” Lisette shrugged again. “He is the second son of a Scots Earl. Myself, I think my lady was jealous. It was not a month before, that M’sieu took a mistress for himself—”

Abigail tried hard not to look shocked.

“And though he was just as generous to her as he had been before, as I say, she is—she was—very young.”

Abigail closed her eyes briefly, seeing—as if with the memory of a nightmare—the blood-engorged face, the bitten shoulders and neck. So distorted had the features been by the blood pooling in the tissues it would have been hard to tell the woman’s age. But it was very much a young girl’s trick, to throw herself at the commander of the occupying troops—a man of power, moderately good-looking, and, as Mademoiselle Droux had pointed out, an Earl’s second son. To seduce him with her gay youth, with her beautiful hair: telling herself that her adventure was for her country’s sake, like the heroine of a play. Yes. She had been very young.

“How old was she?”

“Seventeen, Madame, when she married M’sieu Pentyre. She was twenty when she died.”

Abigail drew in a breath, and let it out, thinking about that very young girl. Had it been her husband taking a mistress, that had determined her on revenge? Yesterday morning, rereading Rebecca’s letters, she had found several accounts of trips to Castle Island, in quest of pamphlet-worthy gossip at the camp. Perdita Pentyre would have seen in her first a kindred spirit, then a link with the Sons of Liberty themselves, the organization whose writings she read with such eagerness. M’sieu would laugh, and kiss her, and she would be wild with indignation, and storm away out of the house . . .

She could almost hear her daughter Nabby shouting at her one day in fury, I’ll show you—!

She was from New York, Abigail recalled; without friends or close connections here to distract her from her adventure. And Colonel Leslie, as she had glimpsed him yesterday, was a well-enough-looking man, and younger than one might expect.
