I've released a new version which supports method_missing like methods.
Here's an example
Detective is now also working with method_missing …

  Detective.view_source('ActiveRecord::Base#find_by_id')

Result

    def method_missing(method_id, *args, &block)
      method_name = method_id.to_s

      if self.class.private_method_defined?(method_name)
        raise NoMethodError.new("Attempt to call private method", 
method_name, args)
      end

      # If we haven't generated any methods yet, generate them, then
      # see if we've created the method we're looking for.
      if !self.class.generated_methods?
        self.class.define_attribute_methods
        if self.class.generated_methods.include?(method_name)
          return self.send(method_id, *args, &block)
        end
      end

      if self.class.primary_key.to_s == method_name
        id
      elsif md = self.class.match_attribute_method?(method_name)
        attribute_name, method_type = md.pre_match, md.to_s
        if @attributes.include?(attribute_name)
          __send__("attribute#{method_type}", attribute_name, *args, 
&block)
        else
          super
        end
      elsif @attributes.include?(method_name)
        read_attribute(method_name)
      else
        super
      end
    end
