After a brilliant military career in India, General Thaddeus Carlyon finally meets death not in the frenzy of battle, but at a London dinner party, in what appears to be a freak accident. But the General's beautiful wife readily confesses that she killed him - a story she clings to even under the shadow of the gallows. Investigator William Monk, nurse Hestor Latterly and Oliver Rathbone, counsel for the defence, work feverishly to break down the silence of the accused and her husband's proud family; and with the trial only days away they inch towards the appalling heart of the mystery.
