A Donnybrook Affair

Lemuel Plant is a hard-up private investigator working out of a shabby downtown office. He's ready to quit, and is determined that his next case will be his last.
Plant is visited by the beautiful Florence Joiner, who wants to collect evidence against her husband, who she alleges is having an affair with his secretary.
On the job, Plant follows Harold Joiner, the managing partner of a successful firm. But he also follows his client, which leads him to the affluent suburb of Donnybrook and its country club. There, Plant discovers there's more to the story than what she disclosed
Intrigue, a compelling plot, and the salacious going-on between the well-heeled people of Donnybrook, make this a must-read for lovers of vintage detective fiction.
