Murder by Medium

Phaedra Thorne, a struggling fake psychic medium is fed up with not being accurate enough in her 'seances' and decides to kill instead, and, for a small fee from the grieving families, use her abilities to 'solve' their murder.

But she's not the murderer, she's enlisted an almost stranger to do it for her and give her just enough details to solve the case without drawing suspicion.

How long can this facade work before the truth comes out or is this the new 'perfect crime'
