Swamped

It looks like... a dead bird? Not like any seabird you've ever seen, though. More like a chicken.

Your first thought is that Mr. William's handmade mask may not be as good as he claimed it to be.

But you've got no time to check, and if you are hallucinating, there's plenty of sailors on this ship you've annoyed over the last few months. One of them is bound to relish the thought of slapping sense back into you. So for the moment, you'll just have to assume this is real.

In that case, what does it mean?

Well, it means there's a trail of feathers, for one. Apparently, whoever killed this chicken wasn't especially concerned with making it tidy. You can't see any conceivable reason why Ms. Becky would want to kill a chicken, but then, you've got no clue as to why she's doing any of this right now. So you may as well pursue this.

The feather trail soon leads to one of the water tanks. There's a feather sticking out of the tank, even.

But there's no sign of anyone. Theoretically, somebody could fit in the tank, but it's not as if there's any opening big enough for a human, and there's too much water to really stay for an extended period of time...

...unless you have a stolen breather mask. So maybe that first assumption is worth a little rethinking, too.

But how could someone even get in here?
