To Arthur Vance — a retired colonel of the United States Army, a man I had always found a little formidable, and had never once had cause to doubt.

I added a single line beneath the picture.

Your grandsons deserve to know the truth about their family.

And then I put the phone down, and I waited, and I did not have to wait very long at all.
