What Was It?
The straw that broke the camel’s back was a dispute over the rent. The Coastal Protection Agency had caught on to the fact that the Cuisniers’ farm was quite prosperous and profitable. More than they ever expected.
So they decided to increase the rent. And they did so unannounced; on top of that, the increase was so significant that it made the Cuisniers think twice about staying on the island. So they ended up leaving.
