Murder Among Friends — Frank McConnell

Things haven't been going well for Harry Garnish...
Instead of becoming head of the O'Toole Investigative Agency, Harry finds himself with a tough new boss -- the surprisingly worldly ex-nun Bridget O'Toole. And then his ex-partner is murdered, and Harry's investigation uncovers dangerous information about the relationships among a powerful local millionaire, a Skokie saloonkeeper, and some pretty heavy players in Chicago's notorious underground. But perhaps worst of all, as Harry dodges bullets and survives several kidnappings, the ever-capable Bridget remains calmly in control and one step ahead of him all the way.
