The Detling Secret // The Detling Murders — Julian Symons

Dark deeds and political intrigues bubble beneath the surface of Sir Arthur Detling's very proper Victorian household.

Sir Arthur Detling, a crusty old Tory, is deeply suspicious of his new son-in-law, Bernard Ross, a Liberal member of Parliament. Do Sir Arthur's misgivings stem only from political differences and the fact that Bernard lacks the right family connections, or is Bernard really up to something sinister?

Another unsuitable marriage in the family, a daughter's defection to London's bohemian art world, and the appearance of Irish terrorists throw Sir Arthur into a tizzy. When two sudden deaths strike the household, however, it becomes apparent that far more than the family's reputation is at stake.
