Young architect Wren Fontaine lands her dream job: restoring Greenleaf House, New York's finest Gilded-Age mansion, to its glory days.
But old homes have old secrets: Stephen Greenleaf-heir to what's left of his family's legacy-refuses to reveal what his plans are once the renovation is completed.
And still living in a corner of the home is Stephen's 90-year-old Aunt Agnes who's lost in the past, brooding over a long-forgotten scandal while watching Wren with mistrust.
Wren's job becomes more complex when a shady developer who was trying to acquire Greenleaf House is found murdered.
And after breaking into a sealed attic, Wren finds a skeleton stuffed in a trunk.
She soon realizes the two deaths, a century apart, are strangely related.
Meanwhile, a distraction of a different kind appears in the form of her client's niece, the beautiful and seductive Hadley Vanderwerf.
As Wren gingerly approaches a romance, she finds that Hadley has her own secrets.
Then a third murder occurs, and the introverted architect is forced to think about people, and about how ill-fated love affairs and obsessions continue to haunt the Greenleafs.
In the end, Wren risks her own life to uncover a pair of murderers, separated by a century but connected by motive.
