The key difference between a suspended-interest lead and other types of leads is the *delayed identification* of the central theme. Other leads, like summary leads, immediately tell the reader what the story is about. Suspended-interest leads keep the reader guessing for a few sentences or even a paragraph before resolving the mystery and connecting the opening to the core subject matter.
For example, a suspended-interest lead might start with a vivid description of a strange object found on a beach, only later revealing that the object is linked to a significant environmental disaster or a missing person case. The initial intrigue holds the reader's attention until the central topic is revealed.
