Regulus of Hogwarts: Lord of the Stars

"When?"

Lucius's eyes brightened, satisfaction flashing and gone, his tone settling back into elegant composure. "Whenever suits you."

Regulus considered. "Tomorrow morning. Come to Grimmauld Place, we'll go together."

Lucius nodded, crisp. "Good. What time?"

"Nine."

Lucius extended his hand, tone back to its usual reserve, a faint smile at the corner of his mouth. "My thanks."

Regulus took it, his own smile just as faint. "Not at all."

They released hands. Lucius stepped back, tapped his cane lightly against the ground, turned, and walked toward Narcissa.

When he had gone some distance, Regulus stood beneath the yew, watching his back.
