What makes Rachel a wonderful guest for this show is her research skills and persistence which led to Solving a Century Old Serial Killer Mystery, The Edgar nominated book The Man from the Train is her first book. She co-wrote with her father Bill James, whose name you might know from Michael Lewis's book and the Movie of the same name Moneyball starring Brad Pitt and Jonah Hill. Rachel is my first amateur detective to come on the show and hopefully, she will not be my last.
