Golden-Age Men of Mystery #2

Chase Yale gets a letter from Red Hawk asking for help. When Chase arrives he finds that the fish have stopped running. Everyone in the village is going to lose their boats to Pierre Grisette, who loaned them money they can't repay, and Red Hawk's people will starve. Pierre has trapped the fish upstream with some whales that are feeding on them. He makes the whales sick by feeding them mustard and making them vomit up precious ambergris. Commando Yank stops him, releases the trapped fish, and Red Hawk keeps the ambergris so that he can sell it and keep his people from starving.
