Angels in the Gloom is the third in Anne Perry's world war one series featuring the Reaveley family. It follows No Graves as Yet & Shoulder the Sky. The Reaveley brothers - Matthew a secret intelligence officer and Joseph, an army Chaplain still seek the sinister Peacemaker - the man behind the murder of their parents and the instigator of the plot to ensure German victory in the war and to carve up the world. A plot that would ruin England's honour.

In Angels in the Gloom, Theo Blaine; a research scientist in Cambridge, who was involved in the development of a new weapon whose successful deployment would ensure victory at sea has been brutally murdered. Joseph Reaveley, recently wounded at the front and at home recuperating is drawn into the investigation. It is not clear whether there is a spy in their midst or whether the murderer is closer to home and the murder for more mundane reasons.

Meanwhile, Matthew is working with the beautiful Irish double agent Detta Hannassey in a battle of wits to determine the cause of arms destined for Britain being sabotaged in US bases and to disguise the fact that Britain has broken German ciphers.

The novel deals with many difficult issues - desertion, loss of faith in such carnage and the role of women in wartime to name but three.

Climaxing with the Battle of Jutland, the novel leaves one looking forward to the next episode - At Some Disputed Barricade.
