After the shattering events of his last adventure, Jimmy is on extended leave from British Intelligence—sliding slowly into middle age, with carpet slippers, tragic sweater and cup of cocoa to match. The formerly sexist superspy is even reevaluating his attitude to women! His daughter (Don’t say it! Don’t you dare say it!) Nancy is taking up the slack in fine style, cutting a bloody swathe through the Regent rogues’ gallery. But a mysterious message starts Jimmy looking into his family’s murky past…where he finds a clue to a strange and deadly new danger.
