Page "Henry Stuart, Lord Darnley" Paragraph 39

A soldier under the pay of Bothwell, William Blackadder of the Clan Blackadder, was allegedly the first non-participant to happen upon the scene, and for that reason was initially treated as a suspect.

Although initially cleared of any involvement in the murder, he was offered up by the conspirators and convicted at a show trial, after which he was executed by being hanged, drawn and quartered before each of his limbs was nailed to the gates of a different Scottish town.
