Phaedrus is a Roman gladiator who has won his freedom. By chance, he is also the exact double of Midir, the Horse Lord, lost King of the Dalriad tribe. To rid the Dalriads of the usurping Queen Liadhan, Phaedrus agrees to a daring pretence -- he will impersonate Midir and become the Horse Lord. Knight's Fee is an exciting story of Norman England, which tells how Ranald the servant boy strives to achieve his ambition and become a knight.
