Aurore said, “I hoped you would come. I couldn’t say this in the house, not with Elizabeth there. I couldn’t do that to Simon. I won’t shame him again!”

He could see her now, the light-colored sweater she’d thrown over her dark dress was a luminous mantle about her shoulders. Her face was even paler, a white oval with dark hollows for eyes. As he came nearer, he could sketch in the details of eyebrows, lips, the curve of her hair, the line of her cheekbone. He could smell her scent, faint and warm, like her breathing.

“Where is your husband? Do you know?”

“He’s in the museum. He has locked me out. He’s taking it very hard, the things Hildebrand has said to him. He thinks he will see me arrested tomorrow.”

“Yes. I know. But Hildebrand hasn’t told anyone else.”

“The story is everywhere, Constable Truit has seen to that. I sent Edith to stay with Mrs. Darley. I didn’t want her to be dragged into our scandal.”

He was on the point of telling her that Simon was missing again, but before he could speak, she had moved closer to him, her hands outstretched, and for an instant he thought she was going to touch him, take his hands in hers or rest her fingers on his forearms. Instead something hard, uneven, brushed against the cloth of his coat. Instinctively he reached out to take it, and his fingers closed over smooth, woven straw. Confused, he ran his left hand over it and realized with cold shock what it was.

A hat. A woman’s straw hat. He could see it more clearly now, the shape and texture, the upswept brim. Ribbons from the crown tangled around his fingers as he turned the hat first this way and then that.

“This is proof that I killed Margaret. It is the hat she was wearing when she left Charlbury. I have kept it, in case of need. The rest of her belongings I burned at the farm, with feathers from a plucked hen we’d eaten fow our dinner. Edith will tell you that it is the same hat that Margaret was wearing when she left, and no doubt Margaret’s maid will confirm that it is hers.” She was silent for a time, and he found himself unable to trust his voice to question her.

“You may arrest me, as you promised, and take me at once to London. I don’t want to see my husband shamed by Hildebrand walking in with all the people in Charlbury goggling, then taking me away with fanfare.”
