The audience is introduced to a young woman, who is reading from her graphic and provoking memoir, titled Blue Barracuda, about time spent as a child prostitute. Her name is Bobbi O’Rourke, and she is later bludgeoned to death with a brick in the alley behind the building.
But, of course, there are many layers to this episode and crime. It turns out that Bobbi is actually a transgender sex worker named Tammy, who was hired by the book's publisher to pretend to be author. The real Bobbi doesn't come outside. Benson & Co. quickly establish that Bobbi wasn’t actually transgender, he just “discovered that he could make more money pretending to be a teenage girl,”
The murder is solved pretty quickly. Tammy was killed by a former client of hers who was shocked to find out that she was a trans woman. He wanted to prove his "wasn't gay."
