First appearance: VII: Miss Joan Merrill

In the storyVII: Miss Joan MerrillOpen this moment free

Joan is taken by Sime and his associates under a ruse—likely told Cheyne has been in an accident and is asking for her—and held drugged and helpless at a house in London. French, walking back to the Yard, quietly reckons her chances are poor, which tells the reader how ruthless the gang has become. Her fate becomes the emotional engine of the middle of the book: Cheyne's hunt stops being about documents and pride and starts being about a person he loves.
