It’s 1886 when Dr Hamish Hart is asked to examine the body of a Chinese businessman found murdered in a Brisbane factory.

Hamish recognises the deceased as the uncle of his childhood friend and makes a commitment to his friend to find the person responsible.

The investigation takes Hamish deep into the secrets of Frog’s Hollow, a smoky world of gambling houses, opium dens and prostitution.

Hamish is forced to navigate a complex array of kinship obligations and family debts to reveal the ultimate truth which he seeks.
