Final answer:
The question does not provide enough information to accurately answer it.
Step-by-step explanation:
In the context of the question, it is not clear who Inspector Braun is. Therefore, without further information, it is difficult to accurately answer the question. However, if Inspector Braun is a fictional character from a book or play, it is possible that he could be investigating or interrogating Masloff and Ross regarding a crime or an incident. This would be a common role for an inspector in detective or mystery stories.
