Whilst a willing suspension of disbelief is often necessary with Father Brown, this episode stretches it to the limit. The story, of a Romani fortune-teller who can apparently predict winning bingo numbers, is intriguing but relies on the obviously flawed premise that such predictions are in any way useful. There are several further plot holes along the way, including the painfully contrived resolution.
The characters, the regulars plus the surprise appearance of a previously unknown sister for Mrs McCarthy, are as delightful as ever and the period Cotswolds setting equally charming ... but the plot holes are big enough to drive the Kembleford bus through. It's better to just enjoy the scenery and try not to pay too much attention to the storyline.
