The mini-series is not expected to make a return.
July 16, 2009
Harper's Island aired on CBS as a 13-episode mini-series, however the show was designed in such a way that it could reinvent itself with a new scenario and location in subsequent seasons.
It is being reported now that chances of that happening are very slim, as ratings for the show were always low.
