The Strange Case of Mrs. Hudson's Cat

The case of the scientific aristocrat --
The case of the missing energy --
The case of the pre-atomic doctor --
The case of the sabotaged scientist --
The case of the flying bullets --
The case of relative jealousy --
The case of the faster businessman --
The case of the energetic anarchist --
The case of the disloyal servant --
The case of the deserted beach --
The strange case of Mrs. Hudson's cat --
The case of the lost worlds.
