I am looking for a book that does not simply state all of the halachis (such as Sefer Chafetz Chaim). Rather what I am looking for is a book that would do something like pose a question or case ("Someone rips you off and you want to warn a relative" or "You suspect someone is physically abusive and you want to make the local Rabbi aware") and then would give a full article on exactly how to go about speaking and or listening sourcing all of the points. Does anyone know of such a book or article?
There are several. One of the best selling in English is probably Chofetz Chaim: A Daily Companion, published by ArtScroll Mesorah Publications.
The book goes through the laws in a format that allows for study of one Halachah or set of Halachoth as part of a daily schedule, and it gives common, practical examples drawn from real life (e.g., company staff meetings) and guides the reader through the application of the laws in the case presented.
I recommend Guard Your Tongue by Rabbi Zelig Pliskin. It goes through several scenarios that are very practical on hilchos lashon hara.
You could also try reading the Chapters 5, 13, 17, 19 and 21 in Journey To Virtue: The Laws Of Interpersonal Relationships, by Avrohom Ehrman (ArtScroll/Mesorah, 2002).
