Theorised narrative


I'm using a case study approach for my PhD and well underway with data collection and analysis. My supervisor has suggested that I write the findings as a "theorised narrative". I've been reading around on this, but wondered if anyone is familiar with this approach and can offer any suggestions for good examples to read an / or any guides on how to write in this style. My subject area is management control, but happy to take any examples in different disciplines. Thanks.
