Complete story — includes the ending
Sherlock and Joan investigate two murders. Sherlock notices that both victims had corneal dystrophy, a rare genetic disorder, which suggests they are related. They discover that they were the illegitimate offspring of a wealthy deceased businessman. His large fortune is to be disbursed to his fraternal twin daughters within days. A witness provides a description of the murderer that matches a woman in a coma—one of the twins. Eventually, Sherlock figures out the comatose woman is working with her doctor, who (having put her in a coma in the first place) can bring her out of it to commit the murders to avoid sharing the inheritance. Sherlock announces in the woman's hospital room that he has identified a third heir and blurts out an address. The killer breaks in, but it is a trap, and she is arrested. Sherlock is also introduced to, and begins working with, NYPD Detective Marcus Bell.
