The papers hinted that behind the deaths of Thomas Barr, M. P. , and his secretary, Sheila Daly, lay scandal and depravity.

P. from his beautiful wife, Camilla, was involved. So was the suicide of the dead secretary's husband. And the seething anger of Martin Kelly, an ex-cop with a grudge. But touching the crime more strangely still was the hundred-year-old mass murder of the Steinberg family... and the sinister trace of soil which had come from atop their grave.
