Grab the missing value after comparing 2 lists

I currently have two lists 

List<string> original = new List<string>();
List<string> edited = new List<string>();


List A            List B
------            ------
   1                 1
   2                 2
   3

I want to grab and display the value that is unable to be matched after comparing (which is 3 in the above example)

var notMatched = original.Except(edited).ToList();

EDIT:

If you have multiple mismatched values with same value and want to be shown just once:

var notMatched = original.Except(edited).Distinct().ToList();

i am not really familiar and into using of lambda expressions. i was thinking of using a foreach perhaps.

Don't need a loop.

    List<string> deletedStuff= new List<string>();
    deletedStuff.AddRange( original.FindAll( x => ! edited.Contains( x ) ).AsEnumerable());
