Detective Wolf and the Flatwoods Fighter

Wolf grabbed the harpoon gun, slipped on the mask, and dove down into the depths. Through the purple mist swaying in his vision, he saw the painting. Before he could grab onto it, he noticed a catfish race towards him, mouth gaped. He ducked and felt the pressure as the catfish sped by. Looking back at the speeding creature, he saw it spin back around to face him. Its beady eyes focused on the painting. and he cursed to himself. The catfish was wider than he was. A sound came up from above. Wolf turned to the underside of the boat. it was rocking, and heavily. Something was wrong. Wolf needed to make a choice. Would he go back to the boat, to help the sailor, or kill the catfish to secure the painting
