This is one of my absolute favourite Modesty Blaise's, simply because the character it focuses on for the duration of the story is Sir Gerald Tarrant. This extremely likeable character well deserves a story all to himself!
This is the seventh book in the series, first published 1973. In many of the books Modesty is either kidnapped by a villain who wants something from her, or blackmailed into working for the Master Villain. This time, it is her good friend Sir Gerald Tarrant who is kidnapped, and held hostage in a remote Chateau in France. Our antagonist in this novel is a strange group; a motley crew with one thread in common; torture and killing. Their plan is to extract information he has gathered on people over the course of his counter-espionage career with the British Foreign Office, then use this information to blackmail people all over the world.
Holed up in the Chateau, Tarrant tries his best to hold out against them, knowing that no-one in the world is aware he has even been kidnapped. Modesty and Willie do track him down, more or less by accident, but in a counter-move, Modesty, Willie, and Lady Janet are all taken captive.
The most enjoyable feature of this book are the parts which are told through the eyes of Sir Gerald Tarrant. For the first time ever, he gets to witness Modesty in action, including a man-to-man, unarmed fight between Modesty and Sexton, a highly trained killer. Both Modesty's ingenuity, and Sir Gerald's appreciation of it, make this an absolute pleasure to read. Last minute twists-and-turns keep this as gripping as ever, and the ending will make you want to laugh out loud!
