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. The book also highlights the beauty of Michigan and its landmarks while going through the twists and turns of a murder-mystery.

“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.
