Episode Description

Picture this: you’re on Mackinac Island having a grand old time at the Grand Hotel, and then boom, a mystery is a foot.

Someone has been murdered during the Mackinac Policy Conference and treachery begins—and if you’re familiar with Mackinac Island, you know you're not leaving unless it's by boat or ferry.  

That’s the premise of a new book called "The Grand Secret" that depicts schemes, betrayal, and, of course, a high profile murder. It's a murder mystery, but "The Grand Secret" also highlights the beauty of Michigan and its landmarks. 

"The Grand Secret" is the work of author Ed McKenna. The Downriver native and Michigan State Graduate has been writing for more than 20 years. 

The father of two joined The Metro to talk more about "The Grand Secret" and why writing matters.

Listen to The Metro weekdays from 10 a.m. to noon ET on 101.9 FM and streaming on demand.
