In this latest, felicitous addition to the Isabel Dalhousie series, our inquisitive heroine comes to see that there are very few of us who are not flawed... herself included. A couple who are old friends of Isabel's ask for her help in a rather tricky situation: A successor is being sought for the headmaster position at their alma mater. The board has four final candidates but has received an anonymous letter alleging that one of them has a very serious skeleton in the closet. Could Isabel discreetly look into it? And so she does. What she discovers about all the candidates is surprising, but what she discovers in herself turns out to be equally revealing — and she finds that she has also unwittingly upset Jamie, the father of her young son. Isabel's investigation will have her exploring issues of charity, forgiveness, and humility as she moves nearer and nearer to some of the most hidden precincts of the heart.
