The Egyptian manuscript

A journey into the past continues.
Two of our contemporaries - the father and the son sent in the nineteenth century, in Egypt, to find an ancient manuscript that could shed light on the mystery intertemporal portal. It will have to cross the desert to sneak into the dungeons of Alexandria and in the crypt of an ancient Christian monastery, to fight the rebels-Arabs on the streets of Basra.
Meanwhile in Moscow in 1887 their friends faced other aliens from the future - with those who are willing to lie, to betray and to shed blood for the realization of their own political ambitions. The novice detective Yasha, a schoolboy Nikolka and their friends face the fierce struggle with extremists from the twenty-first century, as well as with the Belgian adventurer who tries at any price to get the secret passage to the future.
