Short Round

"You discovered the bodies?"
"Yes, sir. Mrs. Pike, there, was with me."
"You found them both dead?"
"Yes, sir...Jimmy and I were pretty friendly at the theater. He was a nice little fellow and seemed grateful that I'd given him his job. We'd only needed one midget for a Oriental scene in the second act and the agencies had sent about fifteen. Mr. Gehring , the director, told me to pick one of them as he was busy and I picked Jimmy because he was the littlest."

"London, England, November 13, 1936: The baffling case of the murder of Andre Marceau, of England, by strangulation, committed apparently by an infant -- though in actuality beyond doubt by a grotesque dwarf or else midget, in infant's clothes -- let down from a hovering Knepp-Chandley autogiro and then whisked away again, is shortly to be completely solved, if the optimistic, and at the same time very positive, statement of Inspector Xenius Jones, youthful crime sleuth from the Bombay, India, police force, and recent addition to Scotland Yard, may be accepted."

- From HSK's The Marceau Case (1936), which can be found here.

It appears that midget murder was abound both inside and outside of the "vicious circle."
