The outrageous and irrepressible Baroness (Ida 'Jack') Troutbeck has another cultural battle to win against the British Establishment: this time, against the horror of modern art. But shortly after she announces this war to her close friends, Baroness Troutbeck is kidnapped.

Panic spreads throughout the London art world when they realise nine more victims are missing, including a corrupted art critic and a famed curator. Could the perpetrator be a traditionalist with a grudge against contemporary art? As the press, art world and police all gleefully predict who might be next, Baroness Troutbeck's sidekick Robert Amiss must work with Scotland Yard to find her. But can they reach her in time?
