Overview:After publisher Serena Darby is found murdered in her apartment, suspicion turns to J.P. Lange, a former professional baseball player acquitted of his wife's murder who had written a book hypothesising how he would have committed the murder. Green and Cassady follow the trail of evidence from Lange to Gerald Stockwell, a former ghostwriter on the book, but Stockwell tries to clear himself by offering McCoy and Rubirosa proof that one of the jurors in Lange's trial was paid off to force an acquittal.
