Ask about the secretary
From Create Your Own Story
"So, what's the scoop on this secretary?" you continue. "Who is she, and why would your husband choose her over a grade-A piece of poon like yourself?".
She scuffed, rolling her eyes. "Some slimy Spaniard girl who came here after the war. I've only had the displeasure of meeting her once, but from what I was able to gather she was a timid little thing."
You grab a notebook from your desk and write down some quick notes. "Got a name and adress for her?".
"No name." she replies with an uninterested look. "But every Thursday around seven, my husband leaves and doesn't return until the next morning. I'm willing to bet my life that he's spending the nights at her place, so if you follow him you're bound to find out where she lives."
