Still another plot line concerns the Kirshner rabbinic succession. The elderly, widowed Rav Kirshner is afflicted with Parkinson's Disease but remains reluctant to hand the reins of power over to his faithful but plodding son Isaiah. Isaiah's ambitious wife, Rachel, resents this, just as she resents her father-in-law's deep affection for his brilliant elder son Jeremy, who left the Kirshner sect to become a college professor. Rav Kirshner dies mid-way through the novel and Rabbi Isaiah launches a vigorous crackdown on perceived laxities within the sect.
