PORTLAND — James F. Timmins recently released his third installment of the Jack Chamberlain series, “HomeGrown.”

The book picks up where fans left Jack, fresh off the case of his life in Boston. Now in Gettysburg with Claire Sanchez for a historic re-enactment, he finds himself on the front lines when the re-enactment turns into a national tragedy. Thrust into the case, Jack must work with local police and the FBI to identify, locate and catch a terrorist cell so insidious it’s been hiding in plain sight. The consequences if he fails are unfathomable, but even success may not be able to undo the damage already caused.

This fast-moving, character-driven story brings readers to the front lines in the fight against homegrown domestic terrorism. With an eye for detail, Timmins switches points of view throughout the book, giving the reader a glimpse into the minds of members of law enforcement and terrorists.

Timmins was born in Old Orchard Beach and still lives in Maine. His first novel “Three Card Monte,” initially written for personal enjoyment, quickly became a favorite of family and friends who urged him to publish it. The second novel, “Marketable,” was written to satisfy the request from fans who wanted more of Detective Jack Chamberlain.

A graduate of Old Orchard Beach High School, Timmins attended business classes at the University of Southern Maine. He has four children.
