ORLEANS – I was meditating at the end of the Rock Harbor jetty, when a passing charter captain scooped me up in a giant net. Suspended precariously above the bay, I paid close attention to the grizzled seaman as he barked out this message: "We all know that the pirate ship Whydah wrecked off Wellfleet in 1717. But did a companion vessel wreck on Pochet Island in the same storm?" My timbers were shivered by this piratical possibility! I whistled for the Curious Prius, which conveniently had just been outfitted for submarine duty. It bubbled up from the briny deep below me. I cut the net with the dagger app on my cell phone and dropped in through the sunroof — we were off!
