“We should not tell Mother,” Amelia hissed, whipping around to face her.

“Ow! Amy, you’re hurting me!”

Amelia reluctantly loosened her grip on her sister’s upper arm. “Listen to me, Milly. You will not say a word to Mother. Not…a…word. Do you understand me?”

Milly’s eyes grew very round. “Then you do think it’s Wyndham.”

Amelia swallowed, unsure of what to do. It certainly looked like the duke, and if it was, surely she had a duty to aid him. Or hide him. She had a feeling his preference would be for the latter.

“Amelia?” Milly whispered.

Amelia tried to ignore her. She had to think.

“What are you going to do?”

“Be quiet,” Amelia whispered furiously. She did not have much time to figure out how to proceed. Her mother would emerge from the dress shop at any second, and then—

Good Lord, she didn’t even want to imagine the scene.

Just then, the man across the street turned and looked at her. He blinked a few times, as if trying to place her in his memory. Stumbled, righted himself, stumbled again, and finally leaned up against a stone wall, yawning as he rubbed his eye with the heel of his hand.

“Milly,” Amelia said slowly. She was still watching Wyndham—for surely it was he—until at the last moment she pulled her gaze away to face her sister. “Can you lie?”

Milly’s eyes positively sparkled. “Like a rug.”

“Tell Mother I saw Grace Eversleigh.”

“Elizabeth’s friend?”

“She’s my friend, too.”

“Well, she’s more Elizabeth’s—”

“It doesn’t matter whose friend she is,” Amelia snapped. “Just tell her I saw Grace, and Grace invited me back to Belgrave.”

Milly blinked a few times; rather owlishly, Amelia thought. Then Milly said, “At this time in the morning?”

“Milly!”

“I’m just trying to make sure we have a believable story.”

“Fine, yes. This time in the morning.” It was a bit early for a visit, but Amelia could see no way around it. “You won’t have to explain anything. Mother will just cluck about and say something about it being curious, and that will be the end of it.”

“And you’re going to just leave me here on the street?”

“You’ll be fine.”

“I know I’ll be fine,” Milly shot back, “but Mother will question it.”

Blast it, she hated when Milly was right. They had gone out for a sweet and were meant to return together. Milly was seventeen and perfectly able to walk three storefronts on her own, but their mother always said that proper young ladies did not walk anywhere alone.

Lady Crowland had not been amused when Amelia had asked her if that included the water closet. Apparently, proper young ladies did not say “water closet,” either.

Amelia looked quickly over her shoulder. The sun was hitting the window of the dress shop, and it was difficult to see inside through the resulting glare.

“I think she’s still in the back,” Milly said. “She said she planned to try on three different dresses.”

Which meant she’d almost certainly try on eight, but still, they could not count on it.
