الموسم 1، الحلقة 14: When a man named Karl Haas ends up in the morgue, it starts an explosive chain of events with Henry and Jo racing to track not just a murderer, but to solve a decades-old notorious art crime. Is Karl a hero, or a traitor and a thief? Karl's son, Erik (guest star Patrick Woodall — The Normal Heart), who is an art dealer, inherited priceless works of art from his father that was stolen by the Nazis during World War II. Meanwhile, Adam (recurring guest star Burn Gorman — Game of Thrones) pays an unsuspecting Abe a furtive visit, and Henry's paternal instincts force a face-off with his nemesis. Flashbacks take Henry to 1814 where he is shocked to learn that his own father's shipping company was involved in illegal and immoral practices. Finally, Abe receives a priceless gift. Guest stars also include Daniel Gerrol (Still Alice, Sisters) as Robert and Harris Yulin (24, Frasier) as Eli.
