The Witches of East Malling

Tempest Michaels is back! His office burned down, his love life is a joke and he's convinced he's getting fat. It's the perfect time for a new case then!
The client is the son of a man who was killed in a freak accident - struck by lightning.
That doesn't sound very paranormal until you learn that he was inside his house when it happened and his heart exploded from his chest. There are eldritch runes drawn on the victim's house and his wife, together with several of her friends, has been seen colluding with a mysterious old crone.
Is there witchcraft being practiced in the nearby village of East Malling? The client certainly thinks so. Will Tempest be swift enough to solve the case before anyone else is killed? Will Frank's witch-sniffer toad sniff out the witch? Will Tempest's gender-neutral assistant turn up dressed as a boy or a girl?
You can bet there will be bedlam as Tempest and his trusted sausage dogs find themselves pitted against another potentially deadly foe.
