Sir,
You don’t know me, but I know your situation – that there’s not been much money in your purse recently. I also know that your wife likes to waste anything you earn in the gambling houses. She promised you to stop, but trust me – she has not. She just got smarter about covering her tracks. As someone who knows the pain of being betrayed, I decided to let you know.
You don’t have to believe me. Just come to Neustadt at night, and bring a ladder with you. There’s a building just by the northern wall of the district. Get on its roof – it offers a very clear view of the gambling den your wife likes to frequent these days.
A friend
