A Simple Mistake

It is a cold wintery night. You are driving on the deserted road towards the familiar hills of Westlake Creek and it isn’t far until you will be home. But then…BANG and a sound of grinding metal! A sudden jolt and you notice smoke is pouring from the hood of your car. You need to call for help. You look around and notice a large mansion house down a gated path. Lights are on so someone must be home. You are thankfully not alone out here. You decide to see if whoever lives there can help. But have you just made a simple mistake?
