Complete story — includes the ending
Wealthy man Titus Delancy is poisoned. He is found wearing a latex bondage suit; an executive at Titus's company dressed the corpse postmortem to get out of paying a $125 million retirement bonus. Someone named Abigail Spencer works under the name Anne Barker as the nanny for Titus's sons. Years before, Abigail was charged with the murder of her father, who physically abused her. At age 15, Sherlock wrote to Abigail under the name "Sean Holmes". Graham Delancy, Titus's teenage son, ends up being his father's murderer. Graham was sexually assaulted by Titus and killed him to save his younger brother from the same fate. Sherlock reveals to Abigail his identity and says that he knows that she killed her father, citing inconsistencies in their letters and the trial. Abigail confesses to Delancy's murder to protect Graham and to pay for her crime, claiming that the victim used her past to try to extort sexual favors. Sherlock warns that he will be watching to ensure that Graham does not commit any further crimes. Sherlock also offers his ear if Graham needs help coping with what he has been through.
