Cost, Matt: - Over the years, Matt Cost (aka Matthew Langdon Cost) has a video store, a mystery bookstore, and a gym. He has also taught history and coached just about every sport imaginable. During those years-since age eight, actually-his true passion has been writing. I Am Cuba: Fidel Castro and the Cuban Revolution (Encircle Publications, March, 2020) was his first traditionally published novel. Mainely Power, the first of the Mainely Mysteries featuring private detective Goff Langdon, was published by Encircle in September, 2020, followed by book two, Mainely Fear, in December, 2020, and book three, Mainely Money, in March of 2021. Also from Encircle Publications are his Clay Wolfe / Port Essex Mystery series: Wolfe Trap (June 23, 2021), Mind Trap (October 6, 2021), and Mouse Trap (April 13, 2022); as well as his new historical fiction novel, Love in a Time of Hate (August 25, 2021). Cost now lives in Brunswick, Maine, with his wife, Harper. There are four grown children: Brittany, Pearson, Miranda, and Ryan. A chocolate Lab and a basset hound round out the mix. He now spends his days at the computer, writing.
