At the rate she was going, Alecto was going to be thrown out of the flat for taking so much time off work, and hence, not getting paid. Good thing she worked for her father, who wouldn't fire her. He knew not to ask questions and understood when Alecto said that she had to take care of some business and needed the afternoon off.
She had spent the morning at work in a daze, trying not to think of the afternoon. Instead she kept forcing her thoughts to return to last night, to Danny. Thinking of him propelled her through the work day, and prevented her from panicking. She assumed that Bellatrix planned a cruciatus session for her. No matter, she could get pain potions and calming draughts, and would just lay low for the next few days. At least, that's what she kept telling herself. And she supposed she deserved it for not keeping her temper in check.
So at a quarter to two, she changed out of her work robes and apparated directly to the Lestrange manor. A house elf showed her inside and summoned the mistress of the house.
