A sniper shoots nine people, killing four, in the financial district. Morland offers his help with the case, knowing the sniper's identity.

During an apparent carjacking gone wrong, both the driver and the carjacker are shot dead. However, many details do not fit that story; for example, the alleged carjacker was left-handed, but the gun ended up next to his right hand. It turns out that the carjacker was actually a hitman hired by the driver's partner in a struggling business. The partner was being pressured by the target to sell some seemingly worthless property. The partner, however, knew that it held rare "old-growth ginseng" wo

Sherlock is furious with Joan because she did not inform him about her recruitment/blackmailing of a person in Morland's organization.

The Russian hitman is arrested, but does not share any usefu

Sherlock disarms the bomb and deduces that it was not arranged by Vikner, but by a rival who wants to frame him and make him the target of Moriarty's vengeance; Moriarty has ordered her organization to not harm Sherlock and Joan.
