Strange Fascination: An Essex Witch Museum Mystery

Its summer in Adders Fork. The sun is out, the sky is blue and things are going swimmingly for Rosie Strange, thank you very much. The Essex Witch Museum has been relaunched with a new Ursula Cadence wing and picnic grounds. 

Then developers roll into the sleepy village to widen the road. When the centuries-old Blackly Be boulder, said to mark the grave of a notorious witch but now in the car park of the Seven Stars, is moved, all hell breaks out. Within hours a slew of peculiar phenomena descends and, when a severed head is discovered atop the boulder, the locals can take no more and storm the Museum to demand someone take action.

Can Rosie and Sam unravel the mystery? And what of the ancient treasure that could drastically change someones fortunes and offer a motive for murder?
