They are close to finding the identity of the "Peacemaker".  The Peacemaker's mission had been to undermine the British war effort and bring Germany and England together.  The Reavleys have been searching for him since he killed their parents at the beginning of the war. Matthew has found a German officer who is willing to go to England and reveal to authorities the identity and mission of the Peacemaker. Before this happens, a young nurse is viciously murdered.  Matthew is charged with the crime.  Joseph and Judith must find the killer to prove his innocence.

This is the final chapter of the World War I saga of the Reavleys.  They come to realize the life they return to will never be the same as it was.   The descriptions of the conditions in the trenches are graphic and horrifying.  The discussion of what war has cost the soldiers and their families is as relevant today as it was then.  This is a powerful finish to what has been an excellent series depicting the lives of a family during World War I.

Highly recommended.
