Nicole Wallace? Who?

A bizarre episode of Criminal Intent last night.

It started reasonably enough with the theft of a diamond by a young Japanese women and the murder of her accomplice. It was going well - Goran was dipping into his vast knowledge of everything to deduce that she wasn't from Japan, but American as she didn't behave like a Japanese lady.

And then suddenly, Eames and Goren decide that something the suspect said reminded them of someone else. 'It sounds like Nicole Wallace' .

It then turned into this cat and mouse game with Olivia D'Abo, who they obviously knew previously and lots of references to previous crimes, which the OH and I knew nothing of. The last time we saw Olivia D'Abo, she was Kevin Arnold's sister and had just brought her hippy lover home to meet her stubborn father.

It was all very fascinating but confusing - it only all became clear when I looked it up on Wikipedia this morning and found out that she was Goran's archnemesis, who had appeared in several previous episodes and will surface in a couple more yet.

So long, Nicole, until the next time.
