Shawn's instruction had followed a different idiom—articulate explanation, with continuing patience (not displayed toward anyone but Ben). Somehow the Irishman conveyed: Let's forget that we seem to be enemies; let's consider this logic of navigation, the sextant, the tiller, the handling of sail, powers of wind and current and the pattern of the clear stars; let's do this as though we were not afraid to turn our backs to each other, you with the knife I let you keep, and I with mine. Ben could respond to this; could not help responding.

The secret whisper continued in the dark.

Ben's body was learning too, his hands calloused and enlarged, his shoulders thickened. Already wiry and tough, he was aware of a burgeoning strength that never reached exhaustion even in the occasional days of bad weather when the mainsail could stiffen and fight back like a living beast. When Ben stripped for swimming, as he had done back there at the island to the amused horror of all aboard, he had noticed a whiplash hardness in leg and thigh, surely much greater than he had possessed a year ago. Ben had been startled to learn—last July, when the Diana put in for careening at another lonely island—that not one other man aboard could swim. So Ben, who had learned it fishlike in the waters of the Pocumtuck River with Reuben darting around him, a little demon of gold and ivory, frolicked alone in the surf and beyond it, amazed and delighted at the buoyancy of salt water and the untiring almightiness of the waves. Even to Shawn it was a mystery. Manuel giggled helplessly. Tom Ball appeared to regard it as a black art.

Once in November, during a lesson on the sextant, Shawn had happened to stretch and flex his shoulders, and Ben discovered that he was fully as tall as Captain Shawn. Another time, Ben spoke with careless sharpness to Joey Mills—the old man's garrulity could be a nuisance—and Joey had drawn back in manifest physical fright, astonishing to Ben until he understood: Well, I could break him in two, couldn't I?

Manuel? One fist, and Manuel would cringe and run.

Ledyard? Maybe, just maybe. That would be a near thing.

Ball? French Jack? Well, hardly. And still, either of them might think twice before starting anything unarmed, or alone.

Dummy? Never, if he got a grip.

Judah Marsh? Why, knives put aside, by God, I could flatten him like a bug, and wash my hands.

Shawn?...
