Disturbing The Peace.
Mackay is temporarily away on a promotion course, but Fletch's joy is short-lived when he finds that the replacement is 'Napper' Wainwright, an extremely harsh officer who makes Mackay look like a pussy-cat. To make things worse, Fletch's ally Mr. Barraclough is transferred to the prison farm. A plan is concocted where the cons start a riot in defiance of Wainwright, and Barraclough steps in to defuse the situation.
