Flying Squadron. The Constantinople Slave

France of the 16th century. The court of Catherine de' Medici, where power is maintained through intrigues and feminine cunning. The flying squadron — four ladies-in-waiting of the queen mother — awaits a new dangerous mission: to find Gabriel de Montgomery — the assassin of the tsar who has disappeared without a trace. His journey leads across the sea, into a world of pirates, slavery, and foreign faith, where every decision could cost a life.
