A superfluity of nuns has descended on Philadelphia, and the city is doing all it can to keep them entertained. The spiritual sisters’ convention lined up several speakers, including media mogul Henry Hare, shock-jock extraordinaire Norm Kevic, and the brilliant sleuth Gregor Demarkian, whose lecture "Investigating the Catholic Murder" is sure to cause a sensation. As a former FBI investigator, Demarkian has plenty of first-hand experience solving heinous crimes-religious or otherwise. And he’s about to get a little more practice. At the convention’s first banquet, one of the nuns drops dead after ingesting the wrong cut of the deadly fugu fish. But was Sister Joan really the target, or was someone trying to do away with the loathsome Mother Mary Bellarmine? All of God’s children may go to heaven – but one of His wives is going to jail.
