Boris Kuester von Jurgens-Ratenicz

Boris Kuester von Jurgens-Ratenicz (Campbell Scott), a fantastically rich German duke with an unpronounceable last name and a lavish estate, is one of the Hamptons' most elite-and mysterious-residents. He also happens to be Hank's landlord. But Boris's luxurious guesthouse, now the Hamptons home of Hank and Evan, comes with some strings attached: as Boris's personal physician, Hank is at the beck and call of the enigmatic billionaire. And Hank's got his work cut out for him, because when it comes to finding a cure for Boris's deadly hereditary disease--and keeping his illness a secret--this ultra-private aristocrat doesn't take breaches of confidence lightly.

Despite his questionable prognosis, Boris seems to have found happiness with Dr. Marisa Casseras, a beautiful and brilliant Cuban geneticist helping Boris find a cure. But her presence at Shadow Pond only complicates Hank and Boris's relationship further, even more so than Eddie's intrusion into Boris's business matters. Hank's outspokenness winds up costing him their business arrangement-and Boris's patronage-until Boris discovers Marisa is pregnant with his child and needs Hank's help caring for them. When Jill winds up being a victim of a suspicious car crash that was originally meant for Boris, Boris finally uncovers the truth about his health...and his family's sinister plot to get rid of him.

With a newborn son and a loving woman by his side, Boris may have finally found some peace-for now. But that doesn't mean he can stop looking over his shoulder to see who might be there to jeopardize his hard-won happiness.
