Sheer Gall / Michael A. Kahn / 308 pages / St. Louis Challenge

Okay, you aren't going to believe this, but the title refers to unadulterated, or pure, cattle gallstones.  I know!  Rachel Gold, Kahn's irrepressible investigative female attorney, is hired to prosecute a soon-to-be ex-husband for spousal abuse.  Attorney Sally Wade shows up in Rachel's office, badly beaten and retains Rachel as her attorney in a suit to acquire assets previously unavailable to her because of a prenuptial agreement.  Sally is murdered.  Is her soon-to-be ex the murderer?  Simultaneously, Rachel is involved in a case of high society fraud.  As always, Michael Kahn entertains as he provides insights into life in St. Louis, the Jewish community/traditions, and friendship in its myriad forms.
