Yes, it was, many thanks MaG.
I am not real keen on Nancy Drew games, it was a gift, some of the puzzles are extremely frustrating and my patience is getting very slim as I age.
I actually went back and finally got that capacitors puzzle done, the reason I hadn't got it was to do with the labels!
I am now about to enter Niko's hideout! Hopefully I won't have any more frustrating moments.
Thanks again, MaG. I wouldn't be able to play these games without your excellent Walkthroughs.
