The Moustache Man Mystery

John Tyler Sanders and his cousin Terry Zander Tyler have a unique relationship as cousins. Who's parents, John's dad is Terry's mothers brother, and Terry's dad is John's mothers brother. The two sets of parents married a year apart.. Now to confuse my readers. John and Terry's grandparents, before their respective adult children married, were widowed, and eventually married each other not long after John and Terry were born.
Two sets of cousins living next door in the same houses their parents grew up in. Grandfather Mike Henry Sanders, and his new bride Tilly Tyler, went on a honeymoon to the Amazon Rainforest that lasted 3 years. Mike Sanders eventually inherits an old run down campground and returns to the states where our story begins.
