The latest chapter in the Euphemia Martins Murder Mystery series.

With the world hanging on the precipice of war, Euphemia learns that threats also lurk on a far more personal level…
When Richenda Stapleford accepts what she believes to be an olive branch from her dangerous and scheming brother, Richard, Euphemia can't help but feel that it's just another act of treachery waiting to unfold. Buying into this uncommon act of kindness, Richenda goes against the wishes of her husband and takes their children to an event at the Crystal Palace, along with Euphemia, Bertram and Rory. As Euphemia learns that the British spymaster Fitzroy is also there, along with an important German delegation, the pieces fall into place and she realises that the implications are dire, both for the future of the Stapleford line and the world at large.
