Seafood Boss, Secret Dragon

Nina Lynn had been married to Finn Chase and was after what he owned. She and Quinn Jones, whose father ran the largest fishing operation in the area, killed Finn and put his body down the Chow ancestral well. Finn's father had hidden the Peerless Dragon Pearl in that well. Finn swallowed it and came back to a point before the killing, able to take the form of a dragon and to move water. The Jones family wanted the pearl and sent people after him. He went down into deep water himself and brought up catches nobody else could reach, which cut into the supply the Joneses had held on their own.
