The Drowner: A Novel - John D. MacDonald

LoL. Every conversation private detective Stanial has with friends, family or acquaintances of the deceased woman turns into some sort of psychotherapist session, in which these people are baring their souls to a man they just have met. 

 

Unfortunately we don´t get to read about Stanials thoughts when he is stuck in such a situation. He might just think: "Oh no, not again".
