Blood is Thinner Than Water

Marleen had everything she could have wanted in her life growing up. A nice house to grow up in, huge birthday bashes every year, and a steady job after graduating from college [with her tuition paid for]. Of course, none of this would be possible without her only surviving family member, her Uncle Jake, taking her in from the tender age of 12 after her parents were murdered and left her an orphan; providing for her and giving her whatever she wanted.

How could he afford raising a child and giving her all of the above and more? What kind of job does he have?

Marleen eventually discovers her uncle's secret profession by mistake. When Jake finds out, will he think that she knows too much? If so, how does he take care of her from that point forward?
