Barnabas, Quentin and the Haunted Cave

Barnabas, Quentin and The Haunted Cave (September 1970)

Harriet Turnbridge asks Barnabas Collins for help after her husband, her brother-in-law, and father-in-law are found dead, their throats savagely ripped open.

The police insist the killer is a mad beast. Harriet thinks that the phantom recently seen at Collinwood is responsible. Barnabas suspects that Quentin Collins, disguised as a wealthy hippie, is guilty.

​Where will they find the murderer? In the nightmare world of Harriet's dreams? In the haunted cave beneath the Collins' family cemetery? Or in another century-when witchcraft and demonology threatened Collinwood?
