Dave Gehrke has been a bartender, real estate broker, horse trainer, sheep farmer, publisher, newspaper columnist, high school economics teacher, school principal and superintendent. And then he "retired". Although often described as the proverbial "jack of all trades, master of none", Dave claims he has secretly spent his working years compiling characters and experiences for what he calls his ultimate career; novelist. Now that he’s completed what he refers to as his "training", Dave has hunkered down with his wife Rita in a small southeastern MN river valley, hunched over his Mac, bolstered with hot coffee and Rita’s homemade shortbread cookies with the sole purpose of grinding out novels until the Grim Reaper stabs a bony finger at the re-boot switch. "Goodbye Ginny Madison" is Dave’s second mystery, following the well-received "Brogan’s Island", a tale of suspense in northern Minnesota. Both novels offer what the author believes makes good mystery reading; life-like compelling characters and plots that twist and turn.
