Brood of Folly — Margaret Erskine

The 1970s are a strange time to be concerned with hundred-year-old family curses. Especially when they were the work of a man like Morton Barnay whose obsession with devil worship and hatred of his sister, Elizabeth Gilderoy, led him to damn her and all her descendants. -- The first wave of fears was a reaction the the strange breakings and enterings. And then Harriet Finch found the body...in the old Varnay Chapel. Chief Inspector Septimus Finch is not about to leave his favorite niece alone to cope with old skeletons, family feuds, witches' covens and the like -- but even he is shocked at the grisly truth behind the family walls.
