The address belonged to a modest blue house with a lawn that needed attention and a child’s toy near the step.

There was nothing secret-looking about it.

That almost made me laugh.

I had carried so much suspicion into an ordinary street that I expected the house to announce its importance somehow.

It did not.

I stood on the porch for several seconds, then knocked.

A woman with tired eyes opened the door.

Her skin looked pale, and one hand rested against the frame, but I could not tell from appearance what her health meant that morning.
