This follow-up to The Bastille Spy promises to be every bit as exciting. CS Quinn, once again, starts with loads of action in The Scarlet Code as Attica Morgan, along with Jemmy Avery with whom she has shared previous adventures, rescues Fleur de Lucile from slave traders in Lisbon. Fleur's husband is hoping to persuade the King to approve The Rights of Man to make all men equal. Naturally this doesn't meet with the approval of the plantation owners and slave traders who abducted Fleur. After rescuing Fleur Attica and Jemmy return to Paris, the scene of previous missions. Fleur is the daughter of an English nobleman and an English spy for The Sealed Knot. In Paris Attica and Jemmy visit a house where the wives of French noblemen are gathered and learn when the plantation owners plan to make a trip to Versailles. Paris is being guarded by revolutionaries making it difficult for noblemen to travel freely however Attica hears where there might be weaknesses in their system. The author then relates the visit of Robespierre, a Parisian lawyer, to Salvatore, an arms smuggler, with information of routes that could double his profits in return for a small favour. On Attica's return to London she makes her way to the premises of The Sealed Knot to meet with Lord Atherton, the married head of the organisation with whom Attica is in love. Catherine Quinn takes her readers along on a fast-paced journey from one adventure to another. This book with its theme of equality and people speaking out against slavery is extremely topical even though it is set more than 200 years ago. I thoroughly enjoyed The Bastille Spy and can't wait to read The Scarlet Code and Attica and Jemmy's latest adventures.
