json.net won't deserialize string

here is my class:
    public class FeedStatusResultMain
    {

        public long feedstatusid { get; set; }
        public long feedid { get; set; }
        public long clientid { get; set; }
        public string clientname { get; set; }
        public string feedname { get; set; }
        public string feeddescription { get; set; }
        public string direction { get; set; }
        public string status { get; set; }
        public string starttime { get; set; }
        public string endtime { get; set; }
        public string nextrundate { get; set; }
        public int summaryprocessed { get; set; }
        public int summaryloaded { get; set; }
        public int summaryrejected { get; set; }
        public string environment { get; set; }
    }

Here is the json response returned from my web service:
"[{
"feedstatusid":92738,
"feedid":143,
"clientid":2,
"clientname":"client1",
"feedname":"report1",
"feeddescription":"report1",
"direction":"O",
"status":"P",
"starttime":"2014-10-23 10:40:32",
"endtime":"2014-10-23 10:40:37",
"nextrundate":"2014-10-23 10:50:32",
"summaryprocessed":3,
"summaryloaded":0,
"summaryrejected":0,
"environment":""
},
{
"feedstatusid":92737,
"feedid":148,
"clientid":2,
"clientname":"client2",
"feedname":"report2",
"feeddescription":"report2",
"direction":"O",
"status":"P",
"starttime":"2014-10-23 10:40:00",
"endtime":"2014-10-23 10:40:07",
"nextrundate":"2014-10-23 10:50:00",
"summaryprocessed":2,
"summaryloaded":3,
"summaryrejected":0,
"environment":""
}]"

I try to deserialize into a list<FeedStatusResponseMain> like this:
List<FeedStatusResultMain> frx = JsonConvert.DeserializeObject<List<FeedStatusResultMain>>(rx);

it throws the following error:
System.ArgumentException: Could not cast or convert from System.String to System.Collections.Generic.List`1[TMSWebServiceClient.FeedStatusResultMain].

I am going nuts trying to find out why this error is happening.  I've tried the JArray.parse() and JObject.parse() methods, but nothing works, just errors.  I don't see anything wrong with the json and the code is right out of their documentation!

The problem is the first and last charachter in the JSON. These extra quotation marks create a different kind of object. Remove these two quotation marks, then it works.

OK!!  I also had to strip out the \ characters from the string ... is there a way to filter these out of the returned json string?  those are the \" double quote escape sequences.

There shouldn't be a need to do this. I would use Fiddler to control what is really sent to you. Those quotes may be from the  VS  debugger.
