Surely where this ADA's live is a Really Small Town. Anabeth knew the victim and all his reletives, because the were to the same school.
I didn't like too much the way the case developed, but i have to say it can happen to anyone. The first suspect, of course is the wife due her backgrounds and the money she will obtain with his husband death. Other topic is the way human nature is set to jump to wrong judgments, even i though it was the wife pursuing the money.
I was amuse how things did turn, how money can turn a reliable guy in to a murderer, and sometimes how a person believe in frienship that i willing to fogive betrayal.
