Diana's altar, paperback/barbara cleverly

Cambridge, 1933.

On All Hallows Eve, in a candlelit pew in ancient All Hallows Church, Doctor Adelaide Hartest witnesses a strangers dying moments.

Adelaide is just in time to hear his final confession: that he has plunged the dagger into his own chest, and that his death will be a suicide, despite its suspicious appearance.

But his confession isnt enough to halt an investigation.

The victim, it is revealed, is known to Scotland Yard, and his death is a matter of national concern.

Assistant Commissioner Joe Sandilands is sent up from London to discover the truth.

Thrown into a deadly ring of cloak-and-dagger intrigue and high-society hedonism, Sandilands chases a phantom killer through Cambridges aristocracy, intelligentsia, cutting-edge researchers, and a clandestine ring of female spies.

What secret was the dead man hiding, and what is at stake?.
