This episode was very different to the usual murder cases investigated by the CSI team and i loved it.
The fact that the writers actually gave Greg the lead role in the episode was brilliant in itself (I feel he is very underused).
When Greg himself became the victim I was horrified, a real nerve-wracking moment for a Greg fan. Overall the case was brilliant and the gang themselves were rather scary, it was great to see Greg take centre stage and i really hope there are more episodes that allow Greg to take the lead. Well done to CSI for this episode possibly my favourite of the season.
