Genevieve Barlow, Eve for short, was an exceptionally strange young lady. She had an alluring and beguiling nature, where for her twenty-four year old self had barely changed in appearance since her eighteenth birthday. She had fooled the administration and had gotten a degree so that she could have a better life.

Most odd of all was that Eve had a secret she shared with no one.

She enters the house of Moriarty, not just to earn but also to find answers on what happened to her mother nearly two decades ago.

Unfortunately, things do not always proceed as one planned. Despite her cautious nature and desire to stay out of sight, a cold pair of eyes falls on her, that soon refuses to leave her out of sight.
