Is There a Burning Manatee in Nessus?

A man says he and his wife had this shop for just under four years. And then she died. We don't get how, but there's an implication of sickness or something along those lines. He said it was a year later that he went to search for her the first time. The other sort of macabre thing here is that Wolf is getting a literal pun on the idea of a fisher of men here.
