The tennis players Claudia Weber and Tara Janssen are playing a tennis match and Claudia wins the game. They are friends and partners in double games. They congratulate each other in the end of the game, and Claudia's father Simon Weber and her husband and trainer Ivan are in the audience. Soon Claudia's body is found inside a ball machine full of blood. Dr. Robbins finds blunt force trauma to her head and a stab wound in her throat. Nick interviews her husband and couch Ivan and the CSIs find the murder weapon in a dumpster, a tennis racket, with Tara Janssen's DNA. Tara says that she used to share her racket with Claudia in double games. The CSIs continue to investigate the evidence and interview the suspects. Until they learn that Simon Weber is not her biological father and connect her to a cold case.
"Double Fault" is an intriguing episode of "CSI". The plot, as usual, has many twists in the investigation and in this show specifically, connection to a cold case. There are many suspects but, in the end, the criminal is not easy to be found. The segment of Hodges and his Italian fiancée is hilarious. My vote is seven.
