The explosion caused the lightest of tremors in the office, her glass of water just barely shivering as Hermione’s brows knitted. It was not until the emerald green death mark rose up in the air that she felt her stomach drop, and her veins ran cold. She walked out of her office without a word of explanation, instead going right to the fire alarm and pulling down on it hard. The alarm began to yell shrilly, muggles rushing out of their offices and running to the fire escape. Hermione watched them go, relieved that they all seemed to be rushing out in the exit opposite of the explosion. They would have been sitting sucks in their offices, at least this way they could scatter or get into cars.
Hermione marched back into her office, pulling her wand out and closing the door behind them. She locked it with a few choice spells, casting a charm on the window to blacken it from the outside. They would be able to see out, but those outside would only see a reflection instead of Hermione and Draco. She was itching to get out, to call Harry or Ron. But the only way to do that was to send her patronus, and that would raise suspicion in the ministry. Besides, there was no way that someone from the government wouldn’t be sent at the sign of a mark.
