CBS have announced their fall (what we call autumn) lineup in the last few days.
Besides the continuing CSI series there's a new one called CSI: Cyber. This is about a "cyberpsychologist" crime solver. What makes this very interesting is the actress who will play her. It's Patricia Arquette who used to be the lead in "Medium".
There's also another NCIS spin-off, this time New Orleans. The lead is Scott Bakula (Quantum Leap and Star Trek: Enterprise).
Whether these new shows will get shown on Channel 5 in due course is unknown but they are worth looking out for.
