Ausable was a shrewd private detective. He did not become panicky on seeing Max with an automatic gun in his room. Even if he were, he did not show it off. Instead, he expressed surprise that he expected him to be in Berlin. He cooked up a nice story that it was the second time someone had broken into his room through the balcony of the neighbouring apartment which reaches down under his window. He expressed his displeasure that he would raise hell with the hotel management for not blocking that balcony. This gave a strong suggestion to Max, that he could have used the balcony instead of the pass key to enter Ausable’s room.
Being a criminal or spy, a person always looks for various routes of escape in times of danger. Very rarely he starts direct encounter risking his life. When Henry, the waiter who arrived with the pre-ordered drinks, knocked, Mr. Ausable simply smiled. When Max asked who it was, he told a blatant lie that it was the police who had come for his extra protection and wouldn’t hesitate to fire as the door wasn’t locked but just closed. Max, assuming that there is a balcony extending below Ausable’s window, jumped. He never knew that it was a suicidal jump from the 6th floor. Thus, Ausable outwitted the spy, Max.
