Determining whom to trust is getting very hard, indeed. This may be the most trying cases imaginable. Director Stone has gone missing and it appears Ministers of Parliament are involved. Xavier is arrested and placed in a jail meant to kill him, while Vic, disguised as a woman, attempts to locate the Minister of External Affairs and ask for his help.
Everyone is called in to assist: Jacko, his wife Alice, their son Pete, Samson the Crime Lord, David and Claire, Tubs and his wife Sara, the boys: Cannon and Ham, plus the bloodhound Arroo.
The Wasp who escaped punishment for her attempts to murder her bigamist husband's first wife last year is back. Vic discovers love letters between Ben, their terrible secretary, and the Wasp. Worse yet, he shared Xavier's financial advice with the Wasp, making her and her husband very wealthy.
With Stone missing, and Barns and Meyers stretched to their limits, Vic decides it's time to train more of the Scotland Yard officers in intuitive and deductive reasoning. While only half the class makes it through her two-day course, everyone is pleased with her results.
Finally, be warned: Vic's sister, Claire, is becoming more difficult than ever. Gregory thinks she is going mad.
