On February 4, 1929, Kate Jackson was attacked at her home in Wales and suffered a head wound. She died six days later. Whodunit? Was it her husband, who relied on her money, but didn't ask about its source? Was a someone connected to her adopted daughter, whose background was never revealed? Was it the former lover who paid Kate thousands of dollars in extortion money over the years? No, he was in prison, but it could have been someone connected to the union he embezzled the money from. Could it have been a jealous lover, another extortion victim, or maybe a wronged spouse? Who was it that wrote those threatening letters, like this one?
"Lest you forget. This is to tell you that we are watching you and we will get you. You husband-stealer. You robber of miner's money that would have fed starving children; you and that man of yours, I suppose he is somebody's husband, too. When we get you we will tar-and-feather you, and for every quid you have taken from us you will get another lump of tar and one more feather. We will show people you are as black outside as you are in. We don't mind doing quod [prison time] for you, you Picadilly Lily. We will get you yet."
The story of Kate Jackson's murder does not provide an answer, but her web of lies and deceit make for a fascinating story at Mental Floss.
