Samuel Black must make a decision: to be a spy like his father or follow his heart.
Either is likely to give his mother chest pains.
For Samuel is no longer a lad with the ambitious and noble wish of being a lamplighter to keep the seedy streets of London safe. About to embark on university, his mind stirs with the thoughts of creating a policing force in London to safeguard its citizens. Held back by his family's legacy as spies, Samuel does not make his ideas known.
But when he stops a would-be purse-snatcher, his path unexpectedly veers into that of one Miss Penelope Paiget, and suddenly, Samuel must make a choice.
To Be a Spy picks up eight years after the conclusion of the Spy Series, a historical romantic suspense series following the adventures of a family of spies during the Napoleonic Wars.
