Henry was a waiter in a gloomy hotel in France. Ausable was a detective staying in the same hotel. One day in his absence, Max used a passkey to get into the room to take a report. When Ausable returned, he saw Max in his room. He knew that Henry would come any time to deliver his drinks.

In reality, there was no such balcony.
