Welcome to Brimstone - a magical town where supernatural creatures live, and where murders are on the increase.

Cassia Winter is the justice witch who investigates crime in Brimstone. She has help from her cat and familiar, Stanley.

This story sees them dealing with the death of a banshee called Dana Murphy.

On the morning of her death, Dana Murphy’s dying scream produces a huge amount of energy that rushes through the town of Brimstone. The energy makes its way to Cassia’s world and sends her flying off her feet. Upon entering Brimstone, Cassia is told that as the town banshee, Dana predicted many deaths - but apparently not her own.

Cassia and Stanley investigate Dana’s death and are confronted with the grim reality of how she died. They discover that more than one resident in Brimstone had a reason to put an end to Dana’s special talent.

As well as dealing with the murder investigation, Cassia is confronted with help from an unlikely source. Stanley immediately feels uneasy, and that unease grows as they delve further into Dana’s murder.
