'Just brilliant.' DONAL RYAN 'An exceptionally good book.' C. J. SANSOM

1816 was the year without a summer. A rare climatic event has brought frost to July, and a lingering fog casts a pall over a Dublin stirred by zealotry and civil unrest, torn between evangelical and rationalist dogma.

Amid the disquiet, a young nursemaid in a pious household conceals a pregnancy and then murders her newborn. Rumours swirl about the identity of the child's father, but before an inquest can be held, the maid is found dead. When Abigail Lawless, the eighteen-year-old daughter of Dublin's coroner, by chance discovers a message from the maid's seducer, she is drawn into a world of hidden meanings and deceit.

An only child, Abigail has been raised amid the books and instruments of her father's grim profession. Pushing against the restrictions society places on a girl her age, she pursues an increasingly dangerous investigation. As she leads us through dissection rooms and dead houses, Gothic churches and elegant ballrooms, a sinister figure watches from the shadows - an individual she believes has already killed twice, and is waiting to kill again...

Determined, resourceful and intuitive, Abigail Lawless emerges as a memorable young sleuth operating at the dawn of forensic science.
