I drove to the house of my closest friend Denise. We had known each other since college.

When she opened the door and saw my face she immediately pulled me inside. I explained everything while sitting on her sofa holding a mug of tea.

“I just sold my company this morning,” I whispered. “Then I walked into my own house and discovered my husband with another woman.”

Denise listened carefully before asking one question. “How long do you think it has been happening?”

“I do not know,” I answered. “That silver car has been there on Thursdays many times.”

That evening I called Robert and told him a simple lie. I said that legal issues with the sale required me to stay downtown overnight.

He sounded concerned and asked if I needed help. His voice sounded calm and affectionate.

After the call I could not sleep. Memories from our entire marriage replayed in my mind.

During the next two weeks I quietly hired a private investigator named Mr Sullivan. I returned home and behaved normally while waiting for answers.

Ten days later Mr Sullivan handed me a thick envelope inside a quiet diner. The woman’s name was Karen Blake and she worked at Robert’s firm as a junior associate.
