Killers lurk around someone's corner, they have to--could it be yours?
Do mystery writers spend time looking at the people around them wondering if someone is a potential murderer?
Is the guy behind you in the check-out line at the movies planning how he might do away with his wife? Or is he just wondering how he let her talking him into bringing 5 little boys to see CARS?
What about the strange kid lurking around the parking lot of the 99 cent store seeming to have an unhealthy interest in the parked cars? Maybe he's been paid to take someone out and he's wandering around trying to boost his courage. Or maybe he's just trying to find an unlocked car with interesting items inside to steal.
The fellow who always has a way of staring lecherously at any woman who comes near him? Is he a rapist just looking for a ripe opportunity? Or is he just a sex deprived male hoping to get this thrills anyway he can?
The grumpy old man who growls at the kids if they come near his house, could he have a horrible secret buried in his basement?
All a mystery writers has to do is look around to find potential killers to write about. What about you? Is there a killer lurking around your corner?
