Photo of the day: Floral Arrangement or Murder Weapon -- You Decide
No clue what these berries are. They look like something growing on a hedge in St. Mary Mead (Miss Marple's village) that she would immediately point out with some quaint name like "oh yes, that's known as the misstress killer. So called after Miriam Clethorne died must unexpectedly right after it became common knowledge that she'd been seen holding hands with Dr. Richardson."
I'd stay away from nibbling on this just in case you've been cheating on someone and have a Miss Marple around.
