You were a lab tech at Hastings Laboratory, the only place you had been able to find work even though you had a Masters in Chemistry, just because you were a woman. None of the other scientists seemed to have any respect for you and you had to conduct your experiments on your own time, after hours at the lab and stealing the equipment you needed from the labs.
One day you made the mistake of 'borrowing' some ribose from Calvin Evans' lab. He was the golden boy of the institute with two Nobel prize nominations for his work and was also famous in the labs for his grudge holding.
A few days later you had forgotten about the whole thing, jumping a little as you heard a voice behind you as you walk into the lab. "There she is... the thief." He says. You turn around, a look of surprise on your face at his voice. "And a secretary no less, what could you possibly need some ribose for anyway?" He scoffs, the demeaning way he says it making your blood boil.
