Tonight’s debut of the CBS series HARPER’S ISLAND will be a bit of a test for some audiences. It’s a sort of AGATHA CHRISTIE meets WES CRAVEN murder and mayhem mash-up that may or may not be a little too graphic for the non-cable crowd. The series is designed to last thirteen weeks with no reprieve. Cast members die each episode with little or no warning. We spoke star KATIE CASSIDY who told us this is a strange gig for her.
