Art and ghostly goings on are the order of the day for Father Brown.
Benjamin Milton is a tortured artist. He has lost his muse Isabella but he sees her spirit wandering around the mansion.
When he unveils a bust of Isabella to the public, it has been damaged. Later art collector Conrad French who is interested in buying up anything related to Isabella is found electrocuted in Milton's studio.
Father Brown was at the public unveiling and knows that Milton is in a bad place especially over the loss of Isabella.
When Milton's former nanny turned housekeeper is found dead, it turns into a murder enquiry.
Suspects range from Milton's sister who is disputing his inheritance to a former model who also posed for Milton and was then discarded by him.
There are several obvious suspects, some good comedy from Inspector Mallory. Yet there is a dark underlying story of abuse, obsession and control. I did like the little twist regarding Isabella.
