In the middle of the night, a hooded stranger arrives on Jason's doorstep begging for help, with a terrifying assassin close on their heels. The stranger is a witch named Leslie Toussaint, and they need Jason's detective skills to find out who sent the assassin.

Leslie is a historian, and they may have stumbled upon a great secret of the past. A secret that someone wants to keep hidden at all costs.

Silvana sees this as an opportunity. A historian could help her finally uncover her own past, and she will take any risk to discover the truth. But will she like what she finds?

Jason must track down who is behind this deadly assassin. More importantly, he must uncover the secret that someone is trying to hide, lest history repeat itself. But Jason has no idea how much this secret could change the world forever.
