Piers Alexander 
Bitter Trade 

In 1688, torn by rebellions, England lives under the threat of a Dutch invasion. Redheaded Calumny Spinks is the lowliest man in an Essex backwater: half-French and still unapprenticed at seventeen, yet he dreams of wealth and title. When his father’s violent past resurfaces, Calumny’s desperation leads him to flee to London and become a coffee racketeer. He has just three months to pay off a blackmailer and save his father’s life — but his ambition and talent for mimicry pull him into a conspiracy against the King himself.
