Constance could hardly believe d'Artagnan's guilt, despite the evidence. If she was being honest to herself, she didn't want to believe it. But it was true. It was dark and outrageous, but it was true. D'Artagnan had murdered Aramis and the Queen.
Under the care of Constance and the two remaining Musketeers, Louis d'Herblay grows up unaware of his nightmarish past. When d'Artagnan escapes from prison, truths are revealed, whispered secrets are undoubtedly found out, and Constance realises that, despite her promises, her godson is quite simply not safe. As Louis uncovers more about his parents and his family, he will discover something that not even Tréville could have predicted.
