Barry’s mentor, Doctor Fingal Flahertie O’Reilly, is going through some personal upheavals as well. After mourning his deceased wife for decades, he’s finally allowed a new woman into his life. But this budding courtship is not going over well with Kinky Kincaid, the doctors’ redoubtable housekeeper, who fears having her position usurped by O’Reilly’s new flame. Tact, diplomacy, and a fair amount of blarney may be required to restore peace to the household.

Meanwhile, life goes on in Ballybucklebo, presenting both doctors with plenty of distractions from their own troubles. From a mysterious outbreak at the local school to a complicated swindle involving an unlucky racehorse, the two partners will need all of their combined wit and compassion to put things right again--just in time for their lives to change forever.
