What gruesome item does one of the witches keep as a charm?

The type of torpedo-shaped glass bottle found in Watford was first manufactured during the 1830s, meaning the find is probably not directly connected with Tubbs. Still, the witch bottle's presence does suggest the building's residents practiced anti-witchcraft traditions much longer than most.

"It's certainly later than most witch bottles, so sadly not contemporary with Angeline Tubbs," Ceri Houlbrook, a historian and folklorist at the University of Hertfordshire, tells BBC News, "but still a fascinating find."
