A Deal With the Grim Reaper

The door which leads to the magical town of Brimstone has gone. Despite its absence, Cassia and her gran find a way into the town using another door.
They are met in Brimstone by the Grim Reaper who tells them of a curse which was cast hundreds of years ago by their ancestor, Gertrude Winter. He explains that if a murder dating back twenty-three years isn't solved immediately, Cassia and her gran will no longer be witches. Not only that, the residents of Brimstone will forget they ever existed.
Gran makes a deal with the Grim Reaper and he gives them more time to solve the mystery. All Cassia has to do is to work out who was murdered, where the deceased body is now, and who did it – all within twenty-four hours. Luckily, she has her cat, Stanley, at her side to help her with this seemingly impossible task.
As they get deeper into their investigation, Cassia and Stanley learn about another deal which the Grim Reaper made – which changes everything.
An intriguing mystery with surprising twists.
