At the end of a long journey, Captain Ahab returns to the mainland to confront the true author of the novel Moby-Dick, his former shipmate, Ishmael. For Ahab was not pulled into the ocean’s depths by a harpoon line, and the greatly exaggerated rumors of his untimely death have caused him grievous harm—after hearing about Ahab’s demise, his wife and child left Nantucket for New York, and now Ahab is on a desperate quest to find them.

Ahab’s pursuit leads him to The Gorgon’s Mirror, the sensationalist tabloid newspaper that employed Ishmael as a copy editor while he wrote the harrowing story of the ill-fated Pequod. In the penny press’s office, Ahab meets George Harrow, who makes a deal with the captain: the newspaperman will help Ahab navigate the city in exchange for the exclusive story of his salvation from the mouth of the great white whale. But their investigation—like Ahab’s own story—will take unexpected, dangerous, and ultimately tragic turns.
