Review: Maigret In Montmartre, Sunday 24th December, ITV

NB: SPOILERS INSIDE Last year, ITV took the bold step of scheduling Maigret’s Dead Man on Christmas Day. Now, for the fourth Maigret film starring Rowan Atkinson, the channel hasn’t gone for the Christmas Day option, instead giving us a seasonal treat on Christmas Eve. And Maigret In Montmartre is a festive treat indeed.
