Can any one name the concise book on Sindh history in English?

I think we have to focus on all aspects of interview i.e. Knowledge and Body Language. For interview knowledge in not important but the expression to deliver that knowledge is important. Retaining, common sense and divertion is prerequisite to pass interview process.

Interview must be from these four sections:

1. Knowledge/Information from Compulsory and Optionals.
2. Current Affairs (Analysis & one liners).
3. Information about Sindh (History & Geography)
4. and most important one is about bureaucracy and about the advertised posts i.e. duties and functions of AC, Section Officer, ETO etc.

Any other relevant information is welcome in this regard.
