Was Houdini murdered?

Was Houdini murdered? | ajc.com: "For all his death-defying stunts, Harry Houdini couldn't escape the Grim Reaper: He died on Halloween in 1926, despite being in extraordinary physical shape at age 52.

But rumors that he was murdered have persisted for decades.

Eighty-one years after Houdini's death, his great-nephew, George Hardeen, wants the escape artist's body exhumed to determine if enemies poisoned him for debunking their bogus claims of contact with the dead."
