Complete story — includes the ending
Gang leader Halcon wants Sherlock to discover who killed the gang's favorite smuggler. Sherlock offers to do so in exchange for the identity of a drug dealer selling poisoned drugs. Halcon instead has the dealer killed. The smuggler's murderer was after the Imperial Jade Seal of China, a valuable artifact, which in actuality is believed to have been carved in the year 221 BC, 221B of course being Sherlock’s address number. Representatives of both mainland China and Taiwan want the seal, the latter offering Sherlock $50 million for it. While examining the site of the auction for the seal, Sherlock notices two indentations on a metal rail under a garage door; they come from an armored luxury car. This leads to Wayne Vachs, the CEO of a large energy company which faces government fines that will ruin it. Vachs won the auction, but did not have the money to pay for it, so he had the smuggler killed. He planned to give the seal back to the mainland Chinese in exchange for a concession on a recently discovered Chinese mineral deposit, worth billions. Sherlock threatens to reveal Vach's identity to Halcon unless he confesses to the police. Meanwhile, Shinwell asks Joan to locate his teenage daughter, with whom he lost touch while being incarcerated.
