The title of this episode seems at odds with the main story at first. Kay Evans is a nervous housewife who wants to report a theft of a suit and a few other items to the police.
However there is something about her story that does not add up. Dixon does some investigations. It turns out that Kay was short of money. Her husband Alf's money for the weekly housekeeping is not enough.
So she borrowed some money from the window cleaner. Now she needs to repay the debt or else he will tell her husband. Alf is already angry that she pawned his suit. Something Dixon found out by visiting the local pawnbroker.
Alf is fuming that his wife has been repaying the loan for months with the added interest. She has paid almost 100% in interest.
Dixon goes to see the window cleaner as he sweet talks his next victim. Dixon demands to see his licence to lend money.
Dixon of Dock Green was never going to be The Bill of its day. That was Z Cars.
With Ted Willis as the creator of the show. Later elevated to be a Labour peer in the House of Lords with an interest in social reform. It is clear that these kind of episodes were more like Call the Midwife. This one raising the social issue of back street moneylenders charging exorbitant interest.
The one bit that sticks out like a sore thumb is Dixon's attitude to domestic violence. 'If I arrested every bloke in Dock Green who socked his wife I'd be working overtime.'
