Over the years, Matt Cost has owned 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, the 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 Money is the third in the Mainely Mystery series featuring private detective Goff Langdon. It was preceded by Mainely Power and Mainely Fear. A new thriller series debuts in June with Wolfe Trap, to be followed by Mind Trap, and Mouse Trap. Cost now spends his days at the computer, writing.
