Herlock Sholmes was a famed CorSec detective. In 821 BBY, he investigated the murder of trillionaire Mr. Tunnels. He considered all of Mr. Tunnels's heirs suspect, including Zorith and Zudu. One by one, the heirs began to turn up murdered. Zudu and Zorith found clues indicating various heirs were guilty, only for those heirs themselves to die. Eventually they discovered that Herlock Shomes was the murderer himself. A Shi'ido, he had been imitating various heirs to claim their shares of the inheritance and make them seem guilty in turn, before killing them.
