The Forgotten Mission - Mitchell Pappas / Long Island Mysteries Revised edition

A WWII cold-case mystery.
What was the deadly secret of Shuller's Land? The last crop on the Long Island farm was planted in 1942, the year the land died from the horror of that one long night.
Decades later, the abandoned weathered barn that leaned precariously from old age still waited for a strong wind to complete the collapse before someone discovered its horrible secret.
Investigator Mitchell Pappas found artifacts at the farm belonging to World War II German spies. So began his mission to unravel the mystery of the forgotten farm and the disappearance of the spies and the farmer's teenage daughter, Melissa.
