A Winded Story
Cade claims that the reason his super-wide brimmed gardening hat was found near the body was because the sudden gust of wind (caused by a windstorm that started around 6pm) blew it off his head and carried it close to the body.
If he’d been wearing his umbrella-sized hat until 6pm as he claims… there wouldn’t have been enough time for the sun to scold his face the way it did.
He must have lost his sun-stopping-sombrero much, much earlier while the sun was still out… when he stabbed the victim through the heart with a golf tee!
The guest’s accusations crossed a line too hard for Cade the Caddie so he took matters into his own bloody hands.
