McGinley foregoes his usual murder mystery genre; instead, he presents an historical novel set during the Anglo-Irish War of 1919 to 1921. The story opens and closes with Declan Osborne in jail, being interrogated by British officers. In between, we learn of the sequence of events that has led him there. Set in Ireland at the time of the Black and Tans, Declan is a young man who sets out to join the cause full of doomed idealism.
