As the Master was to Doctor Who in the old series, so Olivia D'Abo as stone cold killer Nicole Wallace is to Bobby Goren in Criminal Intent. This woman never misses a beat so when she kills again she not only gets herself a rich fiancé to fight off criminal charges, but she provides Vincent D'Onofrio with a great suspect in an anthrax related death.
In all the understandable fear resulting from the 9/11 attacks somehow lost to history was that within a month of 9/11 the anthrax scare occurred. There was also a suspect, a Dr. Stephen Hatfill's name was who the press got a hold of. Then just as swiftly the government cleared him. It maybe the most mysterious story of the new millennia.
James McCaffrey plays the Hatfill character who comes to a sad end, but the whole incident embarrasses the NYPD in general and Robert Goren in particular. All this so D'Abo can stick a finger in Goren's eye. Her character Nicole Wallace does kind of think that way.
I wish they had kept D'Abo around for a few more episodes of CI. She was the best.
