Different people are being killed by a person in a dark hood and no one seems to know why.
The first victim the police find has 3 arrows in the back. He writes on a stone with his blood the letter Wy. The police try to find out if this is a place, an event or part of a person's name.
Murdoch is not getting anywhere with this case. A woman contacts him that says she knows about these killings and Murdoch is going to be one of the victims.
There is a lot suspense in this episode. Murdoch starts to use this medium as a plant in a home that studies the brain.
The series to me has a lot of mystery but hypocritical. Murdoch makes these fast, fake "Sign of the Cross" like a Catholic or Priest like when he gets emotional when he sees a badly hurt person or a dead one but, he gets involved in other things that go against the religion he professes like using mediums an occult religion and listens to their advice. The writers of the show confirm the occult information as credible and believable which I do not believe.
So fake is fake and real is real. Just know this series is based on a detective named Murdoch and not a character who masks as a Catholic.
The good thing about the series is most episodes have a lot of mystery, no swearing, no sexual innuendos.
