The Plantagenets: The Warrior Kings and Queens Who Made England  - Dan Jones

According to the Brut Chronicler, Bishop Burgesch forgot his ecclesiastical dignity completely. He made a bid to flee by running to the lavatory and trying to throw himself down the chute that evacuated human waste to the moat outside.

 

Oh, the drama ;)

 

Going down the lavatory chute might have been the sensible thing to do in his situation, though, being deemed as a traitor to the true king and facing a horrible death. 

 

Stories like this make this book an incredibly fun and entertaining read.
