Was Houdini Murdered?

Today in the news: Was Houdini murdered? Exhumation may bring answer.

To quote the CNN article:

The likeliest murder suspects were a group known as the Spiritualists, which became Houdini's nemesis in his final years. The magician devoted large portions of his stage show to exposing what he said were fraudulent seances by the group. The movement's devotees included Sherlock Holmes author Arthur Conan Doyle.

An unlikely conspiracy theory!

Houdini's nephew and Anna Thurlow (a descendant of one of the Spiritualists) are all for it. I'm just waiting for Doyle's heirs to weigh in...
