Jones is overdrawn at the bank, and after a long investigation Mainwaring discovers that this has been caused by ARP Warden Hodges exorbitantly raising Mrs Pike's rent.
He then convenes a meeting, inviting Wilson, Warden Hodges, the Pikes, the Verger, the Vicar, Frazer, Godfrey and Jones.
Frazer then withheld his rent from Miss Twelvetrees, who could not make her usual donation to the vicar, who could not pay Jones's meat bill.
The meeting hears with horror that Mrs Pike needed the money to pay a huge increase in rent demanded by her landlord, the Warden.
At this, Wilson deliberately gets up, walks slowly but purposefully round the table and punches the Warden in the face, knocking him off his chair.
