From the introduction to the document: Berlin, 1946: The once mighty city lies in ruins, controlled jointly by powers that are Allies in name only. Identical mother-child murders take place on either side of the Russian-American border on consecutive nights. Soviet NKVD and the U.S. Army military police launch a joint effort to find the killer, centered around a burlesque club that’s a hot spot for the resurgent German underworld. In danger of losing their livelihood, the criminals of Berlin suddenly find themselves as eager to find the murderer as their occupiers. Can this hasty alliance find justice, or will it implode under the weight of national intrigue, old grudges, and human greed?
