About the book: 2009 / Having entered the detective secret service of the city diocese of Constantinople-Constantinograd, the former Alexey Smirnov, and now Alexey Paphlagon, rose to the rank of senior tavullarium. So he would have caught dashing people on the streets of the capital of the Roman Empire, but the turbulent times were the 40s of the 15th century. The Turkish scimitar has already been raised over the once great Byzantium, Serbia and Bulgaria have already fallen. This means that Alexy’s road lies in Bulgaria-Rumelia captured by the Ottomans, towards the soldiers of the crusade declared against the Turks by Pope Eugene the Fourth.
