Complete story — includes the ending
Sherlock recognizes the voice of the man who pretended to be Moriarty in the past when the man calls with a ransom demand for a kidnapped child. Moriarty is brought in, though in electroshock hand restraints, to help track down the kidnappers in exchange for favors. The child turns out to be her daughter. Moriarty's lieutenant wants a collection of valuable information Moriarty has amassed over her career. After disabling her restraints, escaping and dealing with all her daughter's abductors, an injured Moriarty allows Sherlock to take her back into custody, predicting that she will be free soon anyway. Sherlock realizes that she may have started to redeem herself; she refrained from killing her head jailer when she escaped.
