Malice in the Palace

The Telegraph is reporting Scotland Yard is investigating an attempt to blackmail a Royal. The Royal cannot be named for legal reasons.

Described at a “50,000 pound sex and drugs blackmail plot,” the two men were arrested by a policeman posing a legal advisor to the Royal who met them at a hotel to view an alleged compromising video tape.

Let the wild speculation begin!

Colonel Mustard with Prince Charles in the stables?
The Princess Royal with a candlestick in the orangery?

Not only is there already a thread about this in IMHO, and not only did the OP there make the same joke, they also used the same Clue character.

Is there some connection between Col. Mustard and the British Royal family I don’t know about.
