Bedsocks and Broomsticks (Omensford 1)

Village Fetes can be murder.
When Fi's electrical powers cause her to be fired from her job, the last thing she wants to do is help the Witches', Wizards' and Warlocks' Institute host the annual Halloween Fete. But when a judge collides with her, she's thrown into a murder investigation...as the prime suspect. Can she clear her name and catch the real killer?
Jam and Jerusalem meets Midsomer Murders meets magic.
If you like cozy British settings, sarcasm and witches, you'll enjoy this series.
