To Timothy Stewart Sedgewick,
When you read this, you will be twelve and a half years old and living on a cul-de-sac in a small brown house your father affectionately calls The Tudor—even though it’s not really a Tudor. To be certain, you still may not be the right Timothy—
please, at your earliest and safest convenience, go out to your driveway and look for the constellation Sagittarius. Look two stars over to the left and watch for a little while. I’ll wait here while you look.
