Detective Kate Beckett's furrowed brow paired with her pursed lips marked her face of confusion and displeasure, which, though accurate, was not entirely true. Hidden behind her expression was a slight feeling of warmth and excitement. Nobody needed to know that. Luckily for Beckett, no one was around to witness that or to ask who had called. They wouldn't believe her if she told them.

Her phone sat in front of her. She had let it fall black as she stared at it, as if staring would bring clarity to the call. She knew Castle was behind it, but how did he manage to program Santa's name, number, and photo into her contacts without her noticing he had her phone?

She shook her head as she snapped back to reality. Paperwork. Oh, and coffee. Definitely coffee.

Beckett stood up from her desk, grabbed her coffee mug, and pushed her chair under her desk with her hip.
