Agatha Raisin & the Haunted House (S03E01)

Agatha sets up her own detective agency, but clients aren’t flocking to her door. To drum up some business, she and James head to Ivy Hall, a residence rumored to be haunted since the English Civil War. As they investigate the eerie noises and mysterious footsteps echoing at night, Agatha begins to wonder if the disturbances are genuinely paranormal or if someone is orchestrating these frightful occurrences to drive the insufferable owner away.
