He may have caught her off guard but as soon as he had her in the alley she had pulled out her little knife and had it pressed against his throat. She wasn't an idiot, she wasn't going to go so deep into Fisher's territory unarmed. For some reason she had not planned on meeting up with Paddy again, she knew he worked for Harry but the Irishman had skipped her mind when she was planning her little reconnaissance mission. "Cousin Percy, how lovely to see you again so soon, and fully clothed too. I was worried that you were still tied to that bed, but I am happy to see you're up and about again."
She was grinning, but only because in that moment she had the upper hand. He may have been stronger than her, but she had the blade to his neck. "Now be a good little boy and let go of me or else I'm gonna have to do something terrible to that pretty throat. And while I was hoping to leave a body on your boss' doorstep, I have a hard time believing he'd be too broken up over it being you."
Delia did not want to kill him, the way they were close his blood would coat her and she didn't want to have to walk home looking like some fright show. But she would do it if he had any thoughts of handing her over to his boss, getting caught by Harry was not the best thing that could happen. Her father would be annoyed as hell and she was doing her best not to upset him lately.
