"Three may keep a secret if two of them are dead." Benjamin Franklin

England, late April, 1926

When Henry Astley, Duke of Sutherland, turns up dead in bed at the end of an afternoon spent calling his family on the carpet, everyone assumes that the excitement finished the old boy off. He was quite old and also quite vociferous in his opinions, so it isn't an unreasonable assumption.

It isn't until the next morning, when the duke's valet and confidant is found shot to death in the hedge maze, that the whole thing takes on a more sinister cast.

Bright Young Thing Philippa Darling, her best friend Christopher and his brother Francis, as well as their parents, Lord and Lady Herbert, have all been summoned to Sutherland Hall for a dressing down. So has cousin Crispin, the future duke, along with his parents, the Viscount and Viscountess St George. Everyone has a string of small peccadillos they're trying to hide, along with a few guilty secrets they don't want anyone to know about. The only question is, which secret was worth killing for?

Pippa isn't worried on her own behalf. She had no reason to want the duke dead. But when it looks like suspicion might fall on Christopher, she has no choice but to step up. She'll sacrifice Francis if she has to, and would throw Crispin to the wolves without a second thought, but Scotland Yard will arrest Christopher over her dead body.

And it might just come to that.
