Lucas Brenner has a car shop, a mailbox, and a debt that won't go away. When an anonymous envelope arrives with fifty thousand euros in cash and a simple instruction -watch a stranger for seven days- Lucas agrees. No questions. No hesitation. Just obedience. But nothing comes without a cost. As more envelopes arrive with increasingly darker orders, Lucas finds himself entangled in a faceless network where no one knows who gives the orders-or why. The chain has no face. Only consequences. Thank You for Your Service is a psychological thriller about obedience, guilt, and how easily we give away our moral choices when someone else takes responsibility. A story where no one pulls the trigger-yet everyone is guilty.
