After years of chilly relations with the Vishwani government, the Foreign Office (and MI5) are invited to the embassy for a formal evening, now that the government has changed hands (MI5 has been asked ""in the new spirit of openness"" to bug the embassy). Unfortunately, terrorists have other plans and besiege the embassy - with agents and their wives still inside. The wives, of course, have all been told something different about where their husbands actually work. Amidst this backdrop, Peter and Dexter must save the day without getting anyone hurt in the process.
