Ed King was a racketeer trying to find a way to bilk the Blair sisters out of their millions. When he saved their cat, he was invited into their home, and since both ladies liked him, he decided to pretend to be twins and marry the both of them, using excuses to be away a week at a time in order to be with his other wife. Ed made a huge mistake while tanning one day, and the sisters soon discovered what was going on, and decided to deal with this bigamist. They took an axe and split him right down the middle....so each would have "half a husband"!; Seven women had been murdered and the Police were baffled by the doughnut-shaped wounds all over their bodies, blood drained and traces of sea brine on their skin and clothing. Danny Hughes, crime reporter, was on the scene and mocked the Police for not having a suspect. The next day, Danny's secretary was murdered in the same way, and was suspected until another killing occured. Danny remembered seeing a strange figure near Pat's home, and when he saw it again, he followed it to an aquarium, and came face to face with a blood-sucking octopus!; Four different people receive to what amounts to anonomous poison-pen letters, each resulting in horrendous events surrounding their families or businesses. Three of the surviving four men meet together and begin to realize that all these recent events were connected by these anonomous letters, and Poppin knew the answer, for he had given the suspect, Ambrose Baldwin, a bottle of disappearing ink, and his letter had now become blank. The men then visited Baldwin...with their own poison pens!; Three medical students play a series of practical jokes using actual human body parts and watching the reactions of various people. The med students roared with laughter, but then seriously wondered what would happen when it was discovered parts of a cadaver was missing, so they went to get the remaining body parts and dispose of them, not noticing a pile of coiled-up intestines that were moving toward them. The next day the Police found the body parts and the students: in a refrigerated unit with the intestines coiled around their necks.
