Yet another fantastic installment of the best show on TV.
The normal character's, Gil Grissom, Catherine Willows, Sarah Sidle, Warwick Brown, Nick Stokes, Greg Sanders, Jim Brass and Dr Robbins are back and in about episode seven (I think) we see a someone from the day shift become more involved with the closely-knit night team. She is not made very welcome by the team but she still remains part of the team (as we can see from season six, currently showing on TV).
This set of episodes gives us brilliant science and also further insight into the CSI's. Catherine is having trouble with her daughter Lyndsey and Greg is tested in his ambitions to get away from the DNA Lab and into the field - things don't always run smoothly.
There are a mixture of entertaining episodes such as 'Who shot Sherlock?' where an avid Sherlock Holmes fan dies in his Baker Street style basement. Was it suicide or murder - this it Greg's final chance to become a CSI. Will he pass??? There are also some more emotive episodes such as 'No humans involved' where a young boy is found dumped along with the rubbish in a back alley. This is testing for Sarah and Brass as they find out the boy has two brothers and they don't know where they are or what condition they are in.
For all of the fans of previous series the serial killer who targets students at a Las Vegas college campus by abducting them near a water fountain after painting railings with the now infamous 'blue paint' is back, even tough someone has already been executed for one of the murders. Is this the real killer? A copycat? Or might they have been partners in crime? When he starts taunting the CSI's it's bound to be an exciting conclusion.
Can't wait for the rest of series 5!!!
