' It's a big brooch. A flower,' replied Kerr. ' But I don't know what kind. Just a flower.'

this story is suspence.
I feel scercely for the husband.
One day, the husband said that his wife didn't come back home. So he wants to search him.
The wife's point is putting on broach of flower,  he said. However the child who saw the wife in the noon said that she didn't put on broach. But the husband said so...
Sadly, they find the wife's dead body. And in another house, her broach throw the garage.
Who did her kill?
