MONMOUTH — Cumston Public Library plans to host Bruce Robert Coffin, award-winning author of the Portland-based “Detective Byron” mystery series at 7 p.m. Monday, March 21, via Zoom.

A former detective sergeant with more than 27 years in law enforcement, Coffin supervised all homicide and violent crime investigations for Maine’s largest city, according to a news release from the library.

His short fiction appears in several anthologies, including Best American Mystery Stories 2016.
