Query: Charming, uncategorizab;e

Alan Bates in top form as a charming, eccentric ex-professor meets Sinead Cusack as a nearly-divorced policewoman with a mind of her own. Bates' character is addicted to puzzles of all kinds, and his search for the author of his favorite crosswords leads to an investigation of a high-level corporate conspiracy. The result is a quirky part thriller, part travelogue, part middle-aged love story, which is utterly British, literate, comic and engaging.As Bates and Cusack travel the length of Britain from Wales to the Orkneys, they interact with characters from all strata of society, reveal their own roots and banter with each other about their encounters and their growing affection for one another. As soon as you relax into the pace of the travelers, the subtlety and brilliance of the acting comes into sharp focus. This is a warm and likable series that bears many viewings.
