The Field Trip Envelope and the Night Lila Jensen Drowned

The morning of the annual spring field trip to the tide pools, Lila Jensen wasn't there. Her blue Subaru was missing from the Spruce Harbour Middle School parking lot, and the substitute science teacher, young and anxious, kept glancing at the clock. The office secretary, Mrs. Duffy, stood pale and silent. A crackling walkie-talkie ordered the buses to hold. Among the students, disappointment rippled. Among the staff, something worse was taking shape.

Only blocks away, Lila's son Tom sat motionless at his mother's kitchen table as two officers prepared to leave. The medical examiner's report would call it an accidental drowning, likely tied to a history of sleepwalking. Minor bruising, no evidence of a struggle, the tub drained, the bath mat wet and tangled, the silver hair trap gleaming clean. The official school email was titled simply "In memoriam, Lila Jensen."

But Tom knew things the official story couldn't explain. Lila never filled the tub before bed. She never left water standing. On field trip nights, she was always up before dawn, itinerary block-printed and double-checked. Her overnight bag sat zipped and ready by the stairs. Her keys lay in the bowl she always kept them in. And her phone showed a text sent at 12:06 AM: "Meeting ran late. See you in the AM. Grier needs my help with those grant numbers."
