"Jannie and Damon, this is the last fleet of working sailing vessels in North America. Can you imagine? These ships have no winches, just manpower and blocks and tackles. The fishermen are called watermen," I told them, just as Nana had told her classes years before.

Then off we went on the Mary Merchant for a two-and-a-half-hour cruise into the past.

The captain and his mate showed us how to hoist a sail with a block and tackle, and soon we had caught a breeze with a loud whoosh and the rhythmic smack of waves against the hull. What an afternoon it was. Gazing up at a sixty-foot mast made from a single log shipped all the way from Oregon. The smells of salt air, linseed oil, residual oystershells. The closeness of my two eldest children, the look of trust and love in their eyes. Most of the time, anyway.

We passed stands of pine woods, open fields where tenant farmers raised corn and soybean, and great white-columned estates that had once been plantations. I almost felt as if I were back in another century and it was a good break, much needed R & R. Only a couple of times did I drift into thoughts of police work, but I quickly pulled myself back.

I half listened as the captain explained that "only boats under sail" can dredge for oysters—except twice a week, when engine-powered yawls were allowed on the bay. I suspected that it was a clever conservation ploy to make the watermen work hard for their oysters; otherwise, the supply might run out.

What a fine day—as the boat heeled to starboard, the boom swung out, the mainsail and jib filled the air with a loud smack, and Jannie, Damon, and I squinted into the setting sun. And we understood, for a little while anyway, that this had something to do with the way life was supposed to be lived, and maybe even why such moments needed to be cherished and remembered.

"Best day of my life," Jannie told me. "I'm not even exaggerating too much."

"Same here," I said. "And I'm not exaggerating at all."

Chapter 91

When we got home early that evening I saw a scuffed-up white van parked in front of the house. I recognized the bright green logo on the door: HOMECARE HEALTH PROJECT. What was this? Why was Dr. Coles there?

Suddenly I was nervous that something had happened to Nana while I was out with the kids. The fragile state of her health had been on my mind more and more lately; the reality that she was in her mid-eighties now, though she wouldn't tell exactly how old she was, or rather, she lied about it. I hurried out of the car and up the front steps ahead of the kids by a couple of strides.

"I'm in here with Kayla," Nana called as I opened the front door and Damon and Jannie slid by me on either side. "We're just kicking back, Alex. No need for alarm. Take your time."
