Wow. What a grid. You caused me no end of trouble, Lebamski, because with the Bob connection the two I was convinced had to be in there were the crossovers!! I eventually got the groups but was unfamiliar with one or two of the components fitting in to the links and I did not identify the Dissolve connection at all (I looked for towns in Norfolk!!) With crossovers and red herrings in abundance, this was a fantastic puzzle. Thank you so much for constructing it.

A toughie, but a goodie! Couldn't get the groups in time, although I was on the right track with 3 of the connections. missed the Cordelia solution. Nice one!
