The Butterfly King - A series exploring the strange death of King Boris III of Bulgaria. With his country hanging in the balance during the bloodshed of World War II, the official record in the decades since his death was that his death was caused by a heart attack. But award-winning journalist Becky Milligan isn’t that convinced.

“Since when does a sudden death span six days?” asks Milligan. “And here’s another thing that strikes me as odd: King Boris’ skin was covered in spots. I’m no Doctor, but it does not sound like a heart attack to me, and I’m not the only one.”

Could he have actually been poisoned? Who could have killed him? And if he was poisoned, why did the official record not reflect that? All episodes are out now.
