"Lord Peter emerged from the bathroom, wrapped in magenta silk, and called for Bunter.
"Bunter, what do you advise in the matter of suitings for a call on an Archbishop whom one suspects of having committed a murder?"
"I regret, my lord, to have seen no recent fashions designed to impress homicidal Archbishops. I would suggest, my lord, any suit which your lordship considers might be said to combine an air of holiness with a certain flavour of the man of action.""
