1883. Thaniel Steepleton returns home to his tiny London apartment to find a gold pocket watch on his pillow. Six months later, the mysterious timepiece saves his life, drawing him away from a blast that destroys Scotland Yard. At last, he goes in search of its maker, Keita Mori, a kind, lonely immigrant from Japan. Although Mori seems harmless, a chain of unexplainable events soon suggests he must be hiding something. When Grace Carrow, an Oxford physicist, unwittingly interferes, Thaniel is torn between opposing loyalties.

The Watchmaker of Filigree Street is a sweeping, atmospheric narrative that takes the reader on an unexpected journey through Victorian London, Japan as its civil war crumbles long-standing traditions, and beyond. Blending historical events with dazzling flights of fancy, it opens doors to a strange and magical past.
