Complete story — includes the ending
At the morgue searching for a case, Sherlock discovers that one of the dead, Leo Banin, is former Russian mafia assassin Vitaly Andropov, who garroted someone the day he died in a motorcycle accident that also claimed a young woman. He was working as a nurse and building a nursing home. Near the scene of the accident lays his victim's body, another hitman who targeted Banin for stealing $30,000 from the mob. Leo was being shot at, and that is what caused the accident. Leo's wife alerted the mobsters to his location. Banin was going to divorce her after discovering her participation in adult films to pay for her passage to the United States, leaving her nothing. He stabbed his first would-be assassin. Banin's wife shot at Banin after the second failed attempt. Meanwhile, Joan's friend asks her to find a one-night stand from a year before. That lover turns out to be Sherlock, who followed Joan at the beginning of their relationship to learn more about her. He reveals his deception to Joan's friend; who responds by sleeping with him again, then tells Joan that she is over him.
