I did not know what the thing in the lake was, but I knew it was dying. The creature had a long black tail and looked like a giant rat. It swam frantically in a tight circle and looked like a dog chasing its tail. But the look in its eyes was not of excitement or play; it was a look of fear and horror. It showed no sign of stopping this odd behavior and, as I watched, it reminded me of a backwoods ouroboros.
