London 1925.
When Adrian Harcourt, a politician and captain in the army believed dead with his company on the battlefield of Flanders, is sighted looking like he's been living rough, Harry Lark, a war veteran and journalist, is enlisted by his friend and benefactor Lady Carlise to investigate.
As he becomes drawn further into the case and the deaths mount up, he can see that things don't add up. Where has Adrian been for so many years? Why can't he remember parts of his past?
Looking further into Adrian's previous life, even as his own dark past and addiction to laudanum threatens to overwhelm him, Harry begins to fall for Lady Carlise's beautiful daughter Freddy, who was also Adrian's fiance.
Chasing the leads as they continue to unravel, can Harry solve the mystery behind what really happened to Adrian before it's too late?
