The author continues to develop the character. This time, Tracy solves a previously solved but disputed death on her own time. However, there is also another death from current times that she and the crew need to solve. She, of course, solves them both with the teams that seems to grow. She's lucky in that she has experts at her disposal but since she's a great problem solver, it seems that the supporting character seem to continue to help. In any case, you come to like the character as a non-perfect human being but a great role model for so many things. Who is perfect? She has flaws but not many and when she stubs the occasional toe, you feel like you can related. Way to go Tracy - keep solving those impossible cases. I'm reading #4 right now!
