Complete story — includes the ending
Silas Cole, a schizophrenic young man, dressed as a knight, wanders into the police station with a gun and states that he had to kill the queen. Silas's ex-girlfriend is dead, shot through the heart. However, Sherlock is convinced that Cole did not kill her; his "knight's code" would have prohibited destroying her heart, thought in medieval times to house the soul. In the course of their investigation, Sherlock unintentionally gets a man fired by revealing he is out on parole. Bell is shot in the stomach, jumping in front of Sherlock when the man comes gunning for him. The victim's heart later turns out to have been enlarged; she was participating in a trial drug program, and her doctor killed her to cover up the drug's failure. Bell asks Sherlock not to come see him anymore during his first hospital visit.
