If that was the French series based on The Killing then I agree it was excellent.Just finished watching a 6 part drama on the Universal Channel called "The Disappearance"..........very, very good (the ending was superb and I admit I cried like). A bit of a slow burner but well worth a watch, I'd give it a 7/10 generally but a 9/10 for the ending.
Excellent acting, particularly both parents and the male, female cop pairing.
