Bring back Harry. The twoparter in this new series is called Change and it has a double meaning. There is change at the lab now that Harry has moved on. Moving in is Jack, an Irishman with a penchant for cage fighting. Jack is just as handsome in the same brooding way as Harry and an intellectual match for his new colleagues, but it will take those who watched for the on-off romance between Harry and Nikki rather than the drama a little longer to get used to the change. And then there is a very complicated case involving the suspicious death of the head of a family ice cream company whose demise leads to a power play for the business.
