Sherlock Holmes: The Serpent's Wake

The Cure is Within Reach. The Conspiracy Runs Deeper.

Safe passage is a memory. Carrying Finch's terrible secret—the Hemlock Key—Holmes and Watson find precarious sanctuary on England's desolate shores, only to discover new horrors await. An SOS from the ship-swallowing Goodwin Sands reveals abandoned Admiralty vessels and whispers of experimental weapons. A derelict radio station broadcasts madness into the marsh, and a reactivated lighthouse hides afflicted souls and watchers in the mist.

As Holmes wrestles with fragmented data, the quest for the counter-agent’s missing components leads them to confront the legacy of reclusive scientists and the monstrous results of forbidden experiments. But who applied the second poison to the chalice? Who sabotaged Station Blackacre? And who is the watcher playing a long game? Besieged in their final refuge, Holmes must solve the ultimate puzzle as the enemy breaches the walls, and the deadliest threat emerges from within their own ranks.
