Reworked Plot

I had to rework the plot for "Who Left the Body in the Garden?" The characters were looking at each other, not moving or talking and at a loss for what to do next. Then I realised my problem. I was trying to write about a normal family, a stay-at-home mom and her children, which I know nothing about. I change the characters to three single sisters with quirky jobs and outlooks, and now I am good to go.
