“I cannot recommend this series enough.”—#1 New York Times bestselling author Ali Hazelwood

Charlotte Holmes’s brilliant deductive skills are tested by a murder at sea—a case that threatens to reveal her secret identity as Sherlock Holmes—in this intriguing Victorian mystery from the USA Today bestselling author of A Study in Scarlet Women.

After feigning her own death in Cornwall to escape from Moriarty’s perilous attention, Charlotte Holmes goes into hiding. But then she receives a tempting offer: Find a dossier the crown is desperately seeking, and she might be able to go back to a normal life.

Her search leads her aboard the RMS Provence. But on the night Charlotte makes her move to retrieve the dossier, in the midst of a terrifying storm in the Bay of Biscay, a brutal murder takes place on the ship.

Instead of solving the crime, as she is accustomed to doing, Charlotte must take care not to be embroiled in this investigation, lest it become known to those who harbor ill intentions that Sherlock Holmes is abroad and still very much alive.
