Alice [Arden or Arderne, 1510-1551] tried for two years to have her husband murdered. She tried to poison him on several occasions. She enjoined her lover in the plot as well as a sworn adversary of her husband, who found two nefarious characters, Black Will and George Shakebag to carry out the deed. They followed Arden around for two days but failed to find an opportunity. Ultimately, Black Will hid in closet while Arden was lured with a game of backgammon with Moseby. Arden had his back turned to the closet and Moseby distracted him by exhorting the predetermined cue to signal Black Will: "Now I may take you, Sir!". Black Will jumped from the closet and strangled Arden with a towel. Mosby struck Arden with a fourteen pound pressing iron. Alice, to make certain that her husband was indeed dead, stabbed him seven or eight times.
Alice Arden was found guilty of the crime of murder and burnt at the stake. Her co-conspirators were all rounded up and executed with various means and at different locations. -- Wikipedia
You can read the whole sorry tale in the Newgate Calendar. It is also the subject of a Renaissance play, Arden of Faversham (The Lamentable and True Tragedie of M. Arden of Feversham, Kent, who was moft wickedlye murdered...etc. etc.), and of Diane Davidson's excellent historical novel Feversham. The photo shows the actual "murder house" (as the tabloids would say), via Faversham.com. (PS: I know the f is really an s, but I don't have a Renaissance s in my font.)
