Dallas works the Delahay case with patient, unglamorous diligence — tracing the express letter, interviewing hotel staff, and corroborating Stevens' evidence with two independent witnesses.

He is the story's steady investigative spine, converting rumor into fact and pressing the mystery forward even as the family tries to look away.
