Heart Break-In

Sarah was wary about letting her husband Tom go on his business trip alone. She had a sneaking suspicion he was having an affair with his secretary, Rachel. Unfortunately, for her sake, she was unable to stop him from going. It was a mandatory meeting, according to the email she was shown.
One night, after Tom had been away for two days, she heard noises coming from the ground floor of her house. Scared, she hid under the covers, afraid for her life.
After what was the longest five minutes of her life, she heard someone come up the stairs, and shortly thereafter heard the bedroom door open. Almost instantly, the intruder flicked the lights in the room on. Knowing that hiding was now pointless, she threw off the covers to face the person.
It was Tom. He was home early.
“Oh God, Tom,” she said as she ran to the door and hugged him. “I wish you had called. I didn’t know you would be home so early. I thought we were being robbed!” she said, letting go of him as he reached into his pocket.
“We are,” he said calmly as he swiftly put the gun he pulled from his pocket to his wife’s head and pulled the trigger.
