Sachiko Kuno and Ryuji Ueno somehow never realized that, in buying not one but two of the biggest historic properties in Georgetown, they’d be the subject of fascination. But now they are, and our colleague Annie Gowen attempts to peel back some of the mystery around these quiet Japanese scientists. Where does the money come from? Why do they keep collecting houses? (No, they did not buy a one just for their cats, contrary to the rumors.) And do they even have time to enjoy them? Meanwhile, Jura Koncius goes inside one of the estates, Evermay, to witness the couple’s elaborate restoration.
