What looks like a drug overdose death of a reformed junkie-turned community activist results in Henry and Jo tracking a murderer. The complex investigation involves dirty dealings between a real estate developer and a community organizer with millions of dollars at stake. Henry flashes back to the same 1890s New York tenement where he worked as a doctor to help the poor, including an orphan boy who gives him a special handmade gift. Meanwhile, Abe cooks up a Sunday dinner feast for Henry, Jo and himself. When Jo tries to find out how the two men know one another, Henry weaves an elaborate tale to cover the truth.

Dr. Tyler Forester, founder of a free medical clinic and the son of a Wall Street billionaire, is awarded one of the city's highest honors for his humanitarian efforts. A few hours later, he is found dead in his tiny apartment. Henry and Jo discover that Tyler's life of privilege and those of his thick-as-thieves Hamilton School classmates took a fateful turn one night many years ago. Now, the nightmare they thought they buried deep within themselves has come back to haunt them. Meanwhile, Henry recalls being faced with the terrible dilemma of being forced to decide between saving a man's life and protecting his own secret. Now, he is faced with the same predicament, but will he come to the same conclusion? And Abe shares a deeply held secret of his own with Henry.
