BAD THINGS HAPPEN IN THREES... 

Clint thought visiting his friend on peaceful Mackinac Island would be the perfect vacation. After all, what trouble could follow him to the middle of a lake? 

But trouble always finds the Gunsmith... And this time, it's a serial killer. There's a whole slew of suspects...the loner, the millionaire, and the entire sanitorium. But there's only one lead: The killer takes three victims a year—and they're all women. Clint and Chief Stewart are searching every inch of the island until justice is served...straight from the end of a barrel!
