More conferences, and more re-writing, had followed the next day, as they’d dropped anchor off Maria Madre (the largest of the islands) and used the longboat to ferry Heavy Objects back and forth between Minerva and shore. Elizabeth and Edmund were confined to their cabins the whole time, and the longboat’s load was covered with sailcloth whenever it was within view of their windows. The cargo hold was off limits to them. There was no way for them to know what had been done. The obvious interpretation was that part of the quicksilver had been taken ashore and buried, and stones brought out from the island to ballast the ship. But it might just as well have been a mountebank’s shell-game: quicksilver-flasks going in to shore and then coming right back out again to be put back in their places in the hold.
