I'm sure you are including "feather" in your "secure". That low to the ground there's no time to troubleshoot so immediately feather the engine and get all the drag out. But if blue line still gives you a descent....your putting that baby down somewhere. Don't forget about figuring single engine service ceiling. Using current weather and weight it will give you an approximate altitude that you should be able to hold with one engine inop. Hard to say on a hot and high day though.
