In Erik Larson's book "Dead Wake: The Last Crossing of the Lusitania," the author describes the haunting image of a trail on the water's surface, reminiscent of a pale scar. This vivid metaphor captures the lingering reminder of something that has disrupted the tranquility of the sea, echoing the ship’s final journey.

The term "dead wake" is used in maritime language to denote this fading disturbance, which could originate from either a ship or a torpedo. It symbolizes the tragic events that unfold as the Lusitania sails into a tense and dangerous situation, foreshadowing the impending disaster.
