Literature & Fiction

Genre Fiction

Review\n"Maybe it was the sleek brown dog with intelligent eyes poised next to the man on the cover. My first impression on beginning read a new mystery novel, "Mainely Power," was this: Boston has Robert B. Parker and Maine has M. Langdon Cost.\nThat initial impression, in some ways, wasn't far off the mark. Parker's hero, Spenser, has his dog, the memorable Pearl, and Cost's hero has his four-footed companion, Coffee Dog. Beyond that, Cost, a onetime bookstore owner in Brunswick has crafted a private detective, Goff Langdon, whom Spenser might well meet for a few beers if a big-city case brought him to town.\n... Langdon is backed by a varied band of friends, male and female, who give real life to the book. Seldom has a mystery focused on men given better, stronger portraits of women than Cost gives of women in this book." 
--Maine Sunday Telegram, Nancy Grape\nMainely Power by Matt Cost"It sometimes strikes me that as we look far and wide for suspense that will captivate us for the duration of a novel or a Netflix series we should look in our own backyard. Fact is, the ingredients of a good crime story--compelling characters, authentic setting, a twisty plot, and a liberal sprinkle of fun--are in our midst. Matt Cost knows this and he offers us new literary acquaintances who lead us around a tweaked version of a place we know well. What better place for a private detective than Brunswick, and what better day job for that detective than a mystery bookstore? In Mainely Power things get very complicated very fast. I settled in with the colorful cast of this midcoast tale and felt that pang that good crime fiction gives you--you bear down on the resolution with the reservation that part of you doesn't want the story to end. And if it does, you hope there's a bookstore in Brunswick where you can find Goff Langdon and a cup of coffee and go over the story yet again." - Gerry Boyle, author of the Jack McMorrow Mysteries\n"Murder, mayhem, and all-around almost gleeful nastiness make this book a fun and crazy read, deeply reminiscent of the hi-jinks found in the best of Elmore Leonard.\nBrimming with hoodlums, hard-as-nails women, vicious oddly-named bad guys, raucous car chases, pistols, rifles, switch-blades and head-splitting blood-letting fisticuffs - the action never stops, but somehow, throughout it all, an underlying layer of sweetness and silliness prevails.\nAs Langdon, with his penchant for bad puns, Sam Spade, and Geary's beer, like Rex Stout's young Archie Goodwin emerging from the big man's shadow, steps up to earn his keep and maybe save the day, it's clear that his life will never quite be the same again.\nHighly recommended for mystery readers, this book is based in the 1990's, yet harkens back to generations past, where dark and smoky bars, a hero with a tough yet charming bluster, and a cold one - will likely get you anywhere."--Terri Portelli, Booklymatters\nWas Harold Dumphy killed to cover up something at the nuclear power plant where he was the head of security?
