When the man pretending to be a waiter saw Zhang Heng getting detained, he silently fled via a nearby flight of stairs. Even in such moments of peril, Zhang Heng remained calm and unruffled. He turned and asked Holmes, "What are the consequences of killing the prime minister's guards?"

"If that's the case, I'll leave it in your capable hands."

Zhang Heng walked back into the box, opened the window, and leaped out of it in front of Holmes.

The guards soon filled the box, but Zhang Heng was long gone. A stricken Holmes, however, was found lying on the ground dumbfounded.
