Sherlock is called by an old acquaintance. An intruder came in a high secured bank and painted a mysterious sign on a painting. The bank wants to know how he did it.
Soon after, the trader working in the office where the intrusion occured, commits "suicide". Or so it seems... He was coming back from a trip in China.
