Reasoning of the killer

When Jane woke up, her head pounded, a dull ache throbbing in her temples. She was no longer in the carriage but in an unfamiliar, dimly lit room. Her hands were bound, and as she struggled to piece together how she had ended up here, panic began to set in. She had been drugged and captured.

"Good, you're awake," came a sudden voice from the corner of the room. Aurora rose from the chair she had been sitting in, her eyes cold and calculating. Gone was the sweet, joyous expression, replaced by an icy detachment that sent shivers down Jane's spine.

Jane's heart pounded in her chest as she tried to make sense of the situation. She demanded, her voice weak from the drug but determined, 

"Aurora, why are you doing this?"

"I thought you were a detective, Jane. You should have figured it out by now, unless you were faking it," Aurora's tone held a scorn as she neared Jane.
