The Most Dangerous Thing — Laura Lippman

Some secrets can't be kept. . . .

Years ago, they were all the best of friends. But as time passed and circumstances changed, they grew apart, became adults with families of their own, and began to forget about the past -- and the terrible lie they all shared. But now Gordon, the youngest and wildest of the five, has died and the others are thrown together for the first time in years. And then the revelations start. Could their long-ago lie be the reason for their troubles today? Each one of these old friends has to wonder if their secret has been discovered -- and if someone within the circle is out to destroy them.
