Moving between high politics and the city’s meaner streets, and filled with memorable characters, Black Drop offers first-class entertainment. SUNDAY TIMES

Leonora Nattrass has written a fine debut that weaves the complex politics of 18th-century Britain into a gripping murder mystery. THE TIMES

Historical crime fiction set in a teeming late eighteenth-century London, as nimbly realised as by the genre’s master, Andrew Taylor. Foreign office clerk Laurence Jago is a reluctant spy involved in arcane skulduggery. THE FINANCIAL TIME

This is a strikingly assured and intelligent first novel about power, conspiracy and the lengths to which the influential will go to ensure their survival. THE LITERARY REVIEW

This is the confession of Laurence Jago. Clerk. Gentleman. Reluctant spy.

July 1794, and the streets of London are filled with rumours of revolution. Political radical Thomas Hardy is to go on trial for treason, the war against the French is not going in Britain’s favour, and negotiations with the independent American colonies are on a knife edge.

Laurence Jago – clerk to the Foreign Office – is ever more reliant on the Black Drop to ease his nightmares. A highly sensitive letter has been leaked to the press, which may lead to the destruction of the British Army, and Laurence is a suspect. Then he discovers the body of a fellow clerk, supposedly a suicide.

Blame for the leak is shifted to the dead man, but even as the body is taken to the anatomists, Laurence is certain both of his friend’s innocence, and that he was murdered. But after years of hiding his own secrets from his powerful employers, and at a time when even the slightest hint of treason can lead to the gallows, how can Laurence find the true culprit without incriminating himself?

A thrilling historical mystery, perfect for readers of C.J. Sansom, Andrew Taylor, Antonia Hodgson and Laura Shepherd-Robinson.

Black Drop is a joy from start to finish. I particularly liked the glimpses of the grubby machinery of government from the inside – you give a real sense of the intrigues behind closed doors… Jago is a very sympathetic hero, with all his flaws, virtues and secrets. And Philpott made me want to smile and cheer alternately — Andrew Taylor, author of The Ashes of London

A gripping, intricate story of Georgian high politics and low life. Leonora Nattrass’s historical spy novel is top notch — W.C. Ryan, author of A House of Ghosts

A riveting political thriller, set at a fulcrum-point in global history. The setting is viscerally immersive and the characters spring to life from the page. This masterful narrative of deception, intrigue and heroism unfolds with compelling pace, wry humour and acute psychological observation. Gripping, moving and utterly engaging — Philippa East, author of Little White Lies

Lovers of historical thrillers have a treat in store. A splendid twisting tale of murder and espionage at the political heart of Georgian Britain — Kate Griffin, author of Kitty Peck and the Music Hall Murders

In Black Drop Leonora Nattrass has done that most dangerous thing: allowed fictional characters to mingle with real ones. I’m far too cowardly to do that in my writing, but she has pulled it off. Well written and well constructed, and Jago is a character readers will certainly want to follow — Alix Nathan, author of The Warlow Experiment

A sparkling evocation of a distant time which is remarkably similar to the current one. I loved it. The sights, smells and eccentricities of eighteenth-century Britain are so perfectly captured that if you’d told me this was one of Dickens’ lost novels I’d have completely believed it. Other fictional worlds are going to seem a lot greyer in comparison — Trevor Wood, author of The Man on the Street
