The whole programme is centred on a murder and finding out who carried it out, with which weapon and in which room. In most cases the murder is usually used as a cover up or a solution for other corrupt behaviour such as blackmailing or theft.
Some viewers may find the portrayal of religious personnel and any other religious connections with murder investigations upsetting, unnerving or offensive.
A couple of episodes feature clairvoyancey which may unnerve some viewers.
