How can I initialize a global nested dictionary around the world?

I have my dictionary declared as follows:

private static Dictionary<string, Dictionary<string, string>> myDictionary;

I want to initialize it globally. The closest I arrived initializes the external dictionary, but still leaves me with a null reference to the internal dictionary:

private static Dictionary<string, Dictionary<string, string>> myDictionary
 = new Dictionary<string, Dictionary<string, string>>();

I need not to initialize it in the method, because I do not want to force the user to call the method before using my class. The user has access only to static methods. I could create a singleton when they call one of the methods, but this one is dirty.

How can I declare both dictionaries globally? Something along the lines of one of them (although not compiled):

private static Dictionary<string, Dictionary<string, string>> myDictionary
 = new Dictionary<string, new Dictionary<string, string>>();

or

private static Dictionary<string, string> inner = new Dictionary<string, string>();
private static Dictionary<string, Dictionary<string, string>> myDictionary
 = new Dictionary<string, inner>();

    static MyClass()

        //Initialize static members here
        myDictionary = new Dictionary<string, Dictionary<string, string>>();
        myDictionary.Add("mykey", new Dictionary<string, string>());
        ...
