It ran from 2002-2005, something like 39 episodes. Pretty much an all Canadian cast that Americans have never heard of.
Sleuth has been showing it in blocks, and I just caught their season finale episode the other night. Excellent show. In 2002, I believe it won Canada's Gemini award for best drama, which I think is like their Emmy award.
Excellent writing, and the only thing formulaic is how the reporters always 'unitentionally' tend to ruin peoples lives. Good times.
