Inspector Cetin Ikmen and forensic pathologist Arto Sarkissian have known each other since childhood and, despite the differences in their religions, races and salary levels, their work has always strengthened their friendship. When both are called to a body in an apartment close to the Topkapi Museum there's no reason to think anything will change. But the case is a strange one. The only person ever seen visiting the comfortable flat is a middle-aged Armenian; the dead boy's limb are atrophied, the flat's window nailed shut. The young man seems to have been a prisoner inside this gilded cage. But why? And for how long? And what, wonders Cetin, is making his old friend Arto, himself an Armenian, so uncomfortable?
