A BRAND NEW SHERLOCK HOLMES MYSTERY — NARRATED BY DR. JOHN H. WATSON.

AN IMMERSIVE MYSTERY ADVENTURE.

Summoned to investigate, Sherlock Holmes and Dr. Watson trace the device to an underground salon known only as The Glass Iris, a place of exquisite secrecy and dangerous indulgence. There, a clandestine circle of thirteen women of dubious means—polymaths, exiled scientists, disgraced aristocrats—use charm, intellect, and engineered influence to extract fragments of the Empire’s most guarded defence: the Iron Gate Protocol.

As Mycroft Holmes reveals the scale of the threat, a shadowy German industrialist—rumoured to be a former protégé of Moriarty—emerges as the mastermind behind the scheme.

To infiltrate this world of seduction, espionage, and mechanical persuasion, Holmes turns to the only ally capable of matching such brilliance: Irene Adler.
