Michael Sarapion, merchant and thief, returns to Byzantine Constantinople from which he fled the year before in fear of his life. In his company is Tobias, the dwarf brother of an icon thief and Ahmed, an Arab galley master with secrets. Michael is filled with grief and fury, intending vengeance for a treasure lost to him twelve years before. He must trust in priests, defy the empire and guard those dearest to him as he searches high and low because he understands that to restore what is rightfully his, he must kill . . . or be killed. In this final installment of The Triptych Chronicle trilogy, Michael, Tobias and the stalwarts of the House of Gisborne-ben Simon will slice a swathe through the Byzantine city, those who challenge them hard upon their heels.
