Christopher Casby is the grasping landlord of the properties in Bleeding Heart Yard.
On the surface, rent-collector Pancks seems like a pretty heartless individual – indifferent to the plight of the poverty-stricken residents of Bleeding Heart Yard. Behind the scenes however, he is being driven by his rapacious employer, Mr Casby, to squeeze the residents for all they are worth. In his private time, Pancks is also a private detective of sorts. He is brilliant at moling out information and piecing together evidence.
