This issue contains two stories: "Deed-a-Day Danny," in which Danny helps a gummy tiger who has lost his teeth by finding him a way to eat, ultimately resulting in the tiger's teeth being cut again; and "The Mistake of Dr. X," in which Sexton Blake and Tinker investigate a warehouse where they discover a rat that triggered a booby trap meant for Dr. X, leading them to pursue the criminal. The second story continues with Blake and Tinker tracking Dr. X through a fire at the wharf, during which they find a telephone that reveals Dr. X's location.
