When a man is found unconscious aboard a steamship to New York, the only clue to his identity is a handkerchief stitched with the initials S.H. — and a mind unlike any other.
Now calling himself Simon Helms, he begins a quiet life working behind the bar of a Lower East Side tavern. But those around him quickly realize there’s something strange about the soft-spoken Englishman. He notices things. Small things. Dangerous things.
When tenants in a nearby building begin dying of what the city claims is typhoid, Simon can’t help but ask questions. And soon, he and Dr. Margaret Walsh — the physician treating his amnesia — are drawn into a web of corruption, chemical poison, and a cover-up that runs deeper than the East River.
He doesn’t know who he was, and he may already be becoming someone else entirely.
A gripping reinvention of Sherlock Holmes — mysterious, slow-burning, and steeped in the grit of 1900s New York.
